Bcash does not work with Jquery

I'm trying to use a bcash cart code on my site, however from what I realized, it does not work when the site uses jquery. I tried on a site with pure html and the link opened normal, but with jquery nothing happens. Does anyone know what it can be?

<form action='https://www.bcash.com.br/checkout/car/' id="form_id" method='post' target='carrinho'>

I tried to use the following code in javascript to try to force the opening, but also nothing:

 $(function(){
    $("#enviadadoscliente").on("click", function(e) {
        e.preventDefault();
        $("#form_id").submit();
    });
});  

Thank you in advance for the help.
