Jquery Uncaught Typeerror In $(selector).on()

I am getting the following error: Uncaught TypeError: ((jQuery.event.special[handleObj.origType] || (intermediate value)).handle || handleObj.handler).apply is not a function This

Solution 1:

Having the event function return false fixed it because the error was somewhere during the propagation of the event and if an event returns false then event.stopPropagation() is "called".
