Having problems with Create Flipbook Component then binding OnFinishedPlaying event.

I create an array of flipbook components(size varies), playing the flipbooks, and then trying to find an OnFinishedPlaying event to them so that I may destroy the components once finished playing.

When binding an event to the completion of the flipbook being played there is no apparent way to pass which component is completing, so I have no way to know which to destroy.
