embebed form in stripe not popping up

I'm trying to set up Stripe into my project but the embebed form never pops out.

view

@foreach ($products as $product)
            <form action="{{ route('pay', $product->id) }}" method="POST">
                {{ csrf_field() }}
                <script
                        src="https://checkout.stripe.com/checkout.js" class="stripe-button"
                        data-key="xxx"
                        data-amount="999"
                        data-name="EXAMPLE.COM"
