List

Hi,
I am creating a list such as follows


var ls:List = new List();
ls.addItem({label:"Apple"});
ls.addItem({label:"Pear"})
ls.addItem({label:"Banana"})
ls.addItem({label:"Grapes"})

addChild(ls);


var btn:Button = new Button();

addChild(btn);

btn.x = 10 + btn.width;
btn.label ="Remove"
btn.addEventListener(MouseEvent.CLICK,onRemoveClick)

function onRemoveClick(e:MouseEvent):void
{
    ls.removeItem(ls.selectedItem);
}

what can i do so that when i click the remove button, the console returns trace statement that prints out all the items that werent removed from the list
