Event names for itween

Hi, this seems to be a simple thing but i can't seems to be find anything related it.

I have a bunch of itween events firing a same oncomplete function. How do i know the name of the particular itween event that triggers it to happen.

Have tried all these but it doesn't work.

 Debug.Log (iTweenEvent.tweenName)?
 Debug.Log (iTweenEvent.eventName)?
 Debug.Log (iTweenEvent.Name)?
 Debug.Log (iTweenEvent.name)?

Please help. Thanks.

Rgds, James
