ActionScript 3.0 :: Randomly Move Object Only After It Plays Animation

What I have is a ninja star that spins around and moves based on the accelerometer of your phone. I created a balloon popping animation and have it all working well. The problem is that as of right now I can either have it be static and animate once the ninja star hits it, or I can have it randomly move and then play the animation which is not what I want. I want it like this: When the ninja star hits the balloon, the animation of it popping plays. And then once the animation is complete, then I want it to randomly move to a new position on the stage. (so the user can hit it again, and so forth...)

Here is my code so you can all take a look.
import flash.sensors.Accelerometer;
import flash.events.AccelerometerEvent;
import flash.events.Event;
var my_acc:Accelerometer = new Accelerometer();
my_acc.setRequestedUpdateInterval(50);
