try place your ad inside a container width id then listen for its click event.
it was something like this but not sure will work. but maybe worth a try

   document.getElementById('adcontainer').onclick = function(){
                                                    clearTimeout(createdtimeout);  //assign your setTimeout to global variable createdtimeout
                                                    custom();
                                                 };
