DataGrid when set variableRowHeight=true, the Image in the itemRenderer can't show up

Question

http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Live Docs_Book_Parts&file=cellrenderer_072_28.html
the above is the flex example. I did my code almost same as
this example. But I do different way in renderer code.
The example:
<?xml version="1.0"?>
<mx:HBox xmlns:mx="
http://www.adobe.com/2006/mxml"
horizontalAlign="center" >
<mx:Image id="albumImage" height="175"
source="{data.Cover}"/>
</mx:HBox>
My code:
<?xml version="1.0"?>
<mx:VBox xmlns:mx="
http://www.adobe.com/2006/mxml"
dataChange="init();">
<mx:Script>
<![CDATA[
public function init():void{
releasedBox.removeAllChildren();
if(data.releasedImage){
var hbox:HBox = new HBox();
var img:Image = new Image();
var lbl:Label = new Label();
img..source = data.Image;
lbl.text = data.Revision;
hbox.addChild(img);
hbox.addChild(lbl);
releasedBox.addChild(hbox);
]]>
</mx:Script>
<mx:HBox id="releasedBox">
</mx:HBox>
</mx:VBox>
The different is I add my image in AS code but not in mxml
code. And the problem is when I set variableRowHeight=true, the
datagrid can display my label, but image can’t display. And
when mouse over, the data line is blinking. When you click one
line, there can show the image for 1 sec.
If I set variableRowHeight=false. It works fine.
Anyone knows what’s this problem? Thanks

Check in the Store menu at the top of your iTunes application on the computer rather than visiting the iTunes Store..
