Problem with event - not working

Hey!

I just registered an event to handle if the Stripe Subscription creation has been successful.

namespace App\Events;

use App\Providers\PaymentReceived;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Laravel\Cashier\Cashier;
use App\Models\StripeProducts;

class PaymentEventListener
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct($user, $payment_method)
    {
        $this->user = $user;
        $this->payment_method = $payment_method;
    }

    /**
     * Handle the event.
     *
     * @param  \App\Providers\PaymentReceived  $event
     * @return void
     */
    public function handle(PaymentReceived $event)
    {
        $companyData = DB::table('companies')->where('user_id', $this->user->id)->first();
        $companySetup = DB::table('company_set_ups')->where('company_id', $companyData->id)->with('plan', 'method')->first();

        $stripe = StripeProducts::where('plan_id', $companySetup->plan->id)->where('billing_cycle_months', $companySetup->selected_payment_plan_cycle)->first();

        $user = Cashier::findBillable($this->user->stripe_id);

        if($user->subscribed($companySetup->plan->name) === false) {
            $user->newSubscription($companySetup->plan->name, $stripe->stripe_price_id)->create($this->payment_method);
        }

        if($user->subscribed($companySetup->plan->name)) {
            // UPDATE Payment Completed
            DB::table('company_set_ups')->where('company_id', $companyData->id)->update([
                'payment_completed' => 1
            ]);
            // ADD ACTIONS
            DB::table('companies')->where('id', $companyData->id)->update([
                'actions' => $companySetup->plan->actions
            ]);

            return response()->json([
                'status' => 1
            ]);
        } else {
            return response()->json([
                'status' => 0
            ]);
        }
    }
}

here is the controller method for the stripe.pay.update.database route

public function stripePayUpdateDatabase(Request $request) {
        return event(new PaymentEventListener(auth()->user(), $request->paymentMethod));
}

Here is the form for the payment submission which is AJAX based

<form id="payment-form" data-secret="{{ $intent->client_secret }}">
<button id="submit_payment" class="stripe-button"><i class="icon-lock text-light"></i>@lang('main.business_setup_payment_card_pay_now') (${{ $setup->calculatePlanPrice() }})</button>
</form>

here is the JS for the form

var form = document.getElementById('payment-form');
var cardHolderName = document.getElementById('cardholder-name');
var clientSecret = form.dataset.secret;
form.addEventListener('submit', async function(event) {
    event.preventDefault();
    $("#card-errors").empty();
    $("#submit_payment").html('<i class="icon-spin5 animate-spin"></i> @lang("main.business_setup_payment_card_pay_button_proccess")');
    $("#submit_payment").attr('disabled', true);
    const { setupIntent, error } = await stripe.confirmCardSetup(
        clientSecret, {
            payment_method: {
                card,
                billing_details: { name: cardHolderName.value }
            }
        }
    );
    if (error) {
        $("#card-errors").empty();
        $("#card-errors").html("<i class='icon-warning'></i> " + error.message);
        $("#submit_payment").html('<i class="icon-lock text-light"></i>@lang("main.business_setup_payment_card_pay_now") ${{ $setup->plan->price * $setup->selected_payment_plan_cycle }}');
        $("#submit_payment").attr('disabled', false);
        $.ajax({
            url: '{{ route("stripe.pay.update.database.errors") }}',
            type: 'POST',
            data: {
                status: error.message
            }
        });
    } else {
        stripeTokenHandler(setupIntent);
        $.ajax({
            url: '{{ route("stripe.pay.update.database") }}',
            type: 'POST',
            success: function(response) {              
                if(response.status == 1) {
                    $("#card-successes").html('<i class="icon-check-1"></i> @lang("main.business_setup_payment_card_pay_success_message")');
                }
            }
        });
    }

});

// Submit the form with the token ID.
function stripeTokenHandler(setupIntent) {
    // Insert the token ID into the form so it gets submitted to the server
    var form = document.getElementById('payment-form');
    var hiddenInput = document.createElement('input');
    hiddenInput.setAttribute('type', 'hidden');
    hiddenInput.setAttribute('name', 'paymentMethod');
    hiddenInput.setAttribute('value', setupIntent.payment_method);
    form.appendChild(hiddenInput);
    // Submit the form
    form.submit();
}

Before event creation it was just a simple route that is returning json response to a AJAX call and it was working perfectly (but insecure) and I decided to move this into an event and now it doesn't work. How can I make this work and also do you have any tips how to improve security for these payments?
