Yakov Would you have a more complete answer of changing the default form submission to an ajax submission?

Something like this should work

 $('#IDOFYOURFORM').on('submit', function (e) {
     e.preventDefault();
     var $form = $(this);
     $.ajax({
         url: $form.attr('action'),
         type: 'POST',
         cache: false,
         data: $form.serialize(),
         success: function (result) {
            //do something with result here

         },
         error: function (xhr, ajaxOptions, thrownError) {
             alert(xhr.responseText);
         }
     });
 });
