Lisetening for Property change

Question

I have created a MC to be used as a button. It is generic and
I customize it per instance. It contains an onRelease event
handler.
I am confused as to what approach I can take within the MC's
onRelease statement that would allow the parent to 1> know the
MC has been clicked & 2> know which instance of the MC has
been clicked (without putting onRelase code for each instance at
the parent level).
I was trying the following...
myMC.onRelease = function() {
_parent.clickedButton = myMC._name;
...but I couldn't figure how to make the parent listen for a
change to clickedButton.
How can I listent for a variable change? Is there a better
approach?
thx,
Nathan

Answer 1

Looks like I can answer my own question. In case anyone else
is confused as to how to do this, I used the Object.watch method.
After doing the above in the MC, I included the following in
the parent...
var btnWatcher:Function = function(prop, oldVal, newVal,
userData) {
trace(newVal);
this.watch("clickedButton", btnWatcher);
