Do you know why the request data is not appaering?

I have a form using stripe. When the pay button is clicked instead of a modal appears in the same page the user is redirected to another page "https://checkout.stripe.com/v3/....html?distinct_id=..." and the modal appears in that page. Do you know why?

The "dd($request->al());" in the RegistrationController@charge is not showing nothing. In the network tab appears:

Request URL: https://q.stripe.com/?event=checkout.config.summary&rf=....? and also appears status code 200.

But the "dd($request->al());" dont appears. Do you know why?

    <form action="{{ route('registration.charge') }}" method="post">
        {{csrf_field()}}
            <script
                    src="https://checkout.stripe.com/checkout.js"
                    class="stripe-button"
                    data-key="pk_test.."
                    data-image="/square-image.png"
                    data-name="Demo Site"
                    data-description="2 widgets (.00)"
                    data-amount="2000"
                    data-image="">
            </script>
    
        <button type="button" href="#step3" data-toggle="tab" role="tab"
                class="btn btn-outline-primary prev-step mr-2">
           Go back to step 2
        </button>
    </form>

I have the route:

    Route::post('/charge', [
        'uses' => 'RegistrationController@charge',
        'as'   => 'registration.charge'
    ]);

In the RegistrationController there is:

    public function charge(Request $request){
        dd($request->all());
    }
