AS3 How to wait for child component to load? - actionscript-3

Question

I have a movieclip, we can call it "mc". On my "mc" is a textarea component called "childta". I am creating instances of "mc" with stage.addchild. All is well and going good but when I add a line of code after that to set the text of "childta" it doesnt show up due to the code being executed prior to it being loaded.
I do know I have the code right because if i click the button to set the text of "childta" it does work. So how can I wait for mc.childta to be loaded?
var mcPM:PMBox = new PMBox();
pmwaiting = 1;
mcPM.name = sendername;
stage.addChild(mcPM);
mcPM.x = 200;
mcPM.y = 200;
mcPM.addEventListener(Event.ADDED_TO_STAGE, pmloaded);
}
while(pmwaiting == 1) {
}
MovieClip(stage.getChildByName(sendername)).pmsa.addText(dArray[3]);
mcPM.removeEventListener(Event.ADDED_TO_STAGE, pmloaded);
}
} else {
//Its chat text, add to window
sa.addText(e.data);
}
}
function pmloaded(Event):void {
pmwaiting = 0;
}

Try listening for "ADDED_TO_STAGE"
childta = new TextArea();
childta.addEventListener(Event.ADDED_TO_STAGE,childtaLoaded);
function childtaLoaded(e:Event):void {
//ready to work with
}
addChild(childta);
