How to integrate Stripe "Pay with Card" in backbonejs - node.js

Question

I am trying to integrate Stripe "Pay with Card" checkout into backbone Node environment. On the server side, I am using Stripe Node code - that part works good. However, on the client side, I am unable to capture the event.
I would like to capture the submit event from the Stripe popup to call "paymentcharge" method in the view.
Here is my code:
<!-- Stripe Payments Form Template -->
<form id="stripepaymentform" class="paymentformclass">
<script
src="https://checkout.stripe.com/v2/checkout.js" class="stripe-button"
data-key="pk_test_xxxxxxxxxxxxx"
data-amount="0299"
data-name="MyDemo"
data-description="charge for something"
data-image="assets\ico\icon-72.png">
</script>
</form>
Backbone View Class
myprog.PaymentPanelView = Backbone.View.extend({
initialize: function () {
this.render();
},
render: function () {
$(this.el).html(this.template());
return this;
},
events : {
"submit" : "paymentcharge"
},
paymentcharge : function( event) {
this.model.set({stripeToken: stripeToken});
}
});
Backbone Model Class
var PaymentChargeModel = Backbone.Model.extend({
url: function(){
return '/api/paymentcharge';
},
defaults: {
}
})
Setup/Call the View from header menu event
if (!this.paymentPanelView) {
this.paymentPanelView = new PaymentPanelView({model: new PaymentChargeModel()});
}
$('#content').html(this.paymentPanelView.el);
this.paymentPanelView.delegateEvents();
this.selectMenuItem('payment-menu');

I think the problem has to do with your View's el and the event you are listening for.
You never explicitly define your View's el, which means it gets initialized to a detached <div> element. You then use your template to fill that <div> with the form element from the template. Even though your <div> is detached, you get to see the content, because you add the content of you el to #content using jquery.
I think the problem is that you are listening for a submit event on the <div> in your el, not the contained <form>. Try changing your events hash to this:
events: {
'submit form#stripepaymentform': 'paymentcharge'
}
Basically, listen for events on the contained element like in jquery's .on. You can also go right to a button click, something like this:
'click #mysubmitbutton': 'paymentcharge'
Hope this helps!
