How to add data to a spark list control dynamically -

i have spark list control(id="cclist") in 1 of custom components() , text input control. when value entered text input, want dynamically add same list control. tried doing following :

protected function cc_selecthandler(event:customevent):void 

{

 var cctext:displayobject = event.data displayobject  cclist.enabled = true;  cclistbutton.enabled = true;   cclist.addchild(cctext); 

}

but error saying "addchild() not available in class. instead, use addelement() or modify skin". tried using addelement, apparently isnt available @ all. idea im doing wrong ?

<s:list x="732" y="299" width="191" height="108" id="lstque"> <s:dataprovider>     <mx:arraycollection>      </mx:arraycollection> </s:dataprovider> 

needs dataprovider use additem method. quick , dirty way add blank dataprovider blank arraycollection enclosed.

example of adding through click event.

protected function imgaddtolist_clickhandler(event:mouseevent):void         {                             this.lstque.dataprovider.additem(datagrid.selecteditem.fldvideothumb);          }
