Flash AS3 - AddChild Outside Of Sprite Range

I am trying to create a dynamic scrolling list in Flash AS3. When I create a list, I set it to be an initial length. Later, I add more objects to the list which is outside of the original size of the list. I want to be able to scroll down the list and see all the objects. My scrollbar just moves the list's y position. However, every object that is drawn outside the original list size is not shown when I run the program and scroll. I have a list object which has the function below when I need to add content to the list. When I initialize the list, I give it an initial height and width which I use to create a mask.

public function AddPlayers(pPlayers:Array, pScrollBar:ScrollBar):void {
var player:Player;
trace("happened again");
for (var i:int = 0; i < pPlayers.length; i++)
player = pPlayers[i];
