I can't understand your problem. Simple example:
If it didn't work:
-Behavior is disabled
-OddConfection to small polygon (if you don't set the polygon it is the whole sprite)
-wrong event to drag the object ... (in simple way you do'n need an event)
-touche event is not recognized (test it with a simple touch-event: clickObject -> write in Log "Object clicked'
For more help we need your code ...
