jQuery's .on() method combined with the submit event
You need to delegate event to the document level
$(document).on('submit','form.remember',function(){
// code
});
$('form.remember').on('submit' work same as $('form.remember').submit( but when you use $(document).on('submit','form.remember' then it will also work for the DOM added later.
I had a problem with the same symtoms. In my case, it turned out that my submit function was missing the "return" statement.
For example:
$("#id_form").on("submit", function(){
//Code: Action (like ajax...)
return false;
})
