jQuery Uncaught TypeError in $(selector).on()

Question

I am getting the following error:

Uncaught TypeError: ((jQuery.event.special[handleObj.origType] || (intermediate value)).handle || handleObj.handler).apply          


        

Answer 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".
