Question

I did everything I could to alert something after submitting a button which has been created in runtime, I gained no success. The code is simple so I don’t post here.
Is there problem with runtime buttons that can’t accept submit event?

$(".simple_btn").click(function(e){
     $("this").submit(function(){
          return false; 
     });
});

The .submit event applies to forms not buttons. So instead of:

$('#btnId').submit(...)

you probably want:

$('#formId').submit(...)

And as far as subscribing to events such as submit to dynamically added elements (that would be a <form> in your case) you could use the .on() method if you are using jQuery 1.7 or the .delegate() method if you are using an older version.

$(function() {
    // subscribe to the submit event of a form with id="formId"
    // that is either currently present in the DOM or it will be
    // added dynamically in the future
    $(document).on('submit', '#formId', function() { 
        // the form was submitted => do some processing ...
    }); 
});

And here’s a live demo in which we use the .on() method to subscribe to the submit event of a form that is dynamically added to the DOM at a later stage.
