Can't render multiple PayButtons

[StarpTech]

Hello
I can't create multiple payButtons via an Angular directive because all buttons will be append to the latest form and I can just buy the latest product. Do you know anything about it?

Directive template:

<form method="post" ng-submit="submit($event)">
    <script
        src="https://button.paymill.com/v1/"
        id="button-{{product.id}}"
        data-title="{{ product.title }}"
        data-description="{{ product.description }}"
        data-amount="{{ product.amount }}"

        data-elv="{{ config.elv }}"
        data-label="{{ config.label }}"
        data-submit-button="{{ config.submitBtnText }}"
        data-inline="{{ config.submitBtnInline }}"

        data-public-key="{{ paymill.publicKey }}"
        data-lang="{{ paymill.language }}"
        data-logo="{{ paymill.logoUrl }}"
        data-currency="{{ paymill.currency }}"
        >
    </script>
</form>
