Actionscript 3 :: AddEventListener Not Detecting Children (even With Bubbles)

I have a sprite called content.In this sprite there are multiple children that I add and remove (lot's of traffic there)these children dispatch events that bubble.I have an event listener listening to content and checking for the same type of event.[code]But the problem with the second model is that I would have to track every time something is changed in the children tree and add the event listener which kinda defeats the entire purpose of bubbling for me.
