Using promises with ajax in change events

Vote count: 0

Say you execute an ajax request upon a change event like so:

MyClass.prototype.bindChangeEvent = function(){
  $(document).on('change', '#elementid', function(){
    var $element = $(this);
    $.ajax({
      url: '/someurl'
    });
  });
}

Now, in client code, How can you attach to that ajax promise the done/fail/always callbacks?

You can't return the promise from the ajax request because its only created on the change event.

Is there a way to create a promise ahead of time and tell jQuery to use that promise for a particular ajax request?
