get reference of jquery ui object in touchend
===

I am using https://github.com/furf/jquery-ui-touch-punch to map the touch events. jQuery UI droppable has the below code in which the event and ui objects are passed automatically. I want to write a custom handler to which I can pass the same objects. Could any one suggest how I can get the reference of ui object on touchend event on IPAD ? So that I can use same drop function for both desktop and IPAD.   



    drop: function(event, ui) {
        	dropFunction(event, ui);
        }

so on touchend event I can call dropFunction(event,ui)
