Are you using one of the free Shopify themes? I'm using the "Simple" theme and was having a problem with this. Here's how I got it to work:

Change:
$('form[action="/cart/add"]').submit(function() {
to:
$('#AddToCart').on("click", function() {

There seems to be a name conflict with the .submit() method and the form's submit button name="submit" attribute. SO reference here.

Thanks for your post @ajisilva. I am using this with the Simple theme and will try your change. Thanks again!
