Can't open popup window in item renderer

Question

I have a datagrid with two columns. Each column has it's own
itemRenderer. The itemRenderers have there own class. In one
itemrenderer I have a link button and it has a click event that is
associated with it in the script block of that class. Inside the
click event I have the following code to create a popup:
var popup_win:MyWindowType = MyWindowType
(PopUpManager.createPopUp (this, MyWindowType , true));
When I click the linbutton I will see a flash and a blur
affect as if the window is trying to open but never does. I've
traced "this" and it's the renderer... So I tryed to reference back
up the that class that has the datagrid control... which is
this.parent.parent.parent... but that doesn't work either. I'm
basically trying to open a window that allows the user to choose
some stuff from a radio button and then when they click ok on the
popup window it does some validation and then the contents get's
changed in the cell that it came from. I want the popup to open
upon clicking of the link button or else I would use the editor
functionality. Any ideas of how I could do this?

Good Day
I had the same idea for an itemrenderer....but I'm using the
mouse_over event.
A titlewindow pops up when moving over a row in the datagrid,
and closes when moving out.
The intent of the popup is to show some charts and additional
links.
However, when the popup shows, and I move my mouse into the
popup box, the mouse movements are still being registered by the
datagrid row below the popup box...hence making a new popup box
appear every time I move the mouse.
I tried to set focus on the popup alone...but still doesn't
work.
Here's the itemrenderer code:
<mx:Text xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="_OnCC()" mouseOut="_mOut()">
<mx:Script>
<![CDATA[
import mx.core.Application;
import flash.events.MouseEvent;
import mx.managers.PopUpManager;
//import mx.controls.Alert;
private var pop1:_popup_gridb;
public var currentColumn:String = "";
public function _OnCC():void{
var currentXml:XML = new
XML(data..field.(@columnname==currentColumn));
text = currentXml.@value;
text = text.toUpperCase();
addEventListener(MouseEvent.MOUSE_OVER, _mOver);
//addEventListener(MouseEvent.MOUSE_OUT, _mOut);
private function _mOver(event:MouseEvent):void{
//Alert.show("Hello World");
pop1 = _popup_gridb(
PopUpManager.createPopUp(DisplayObject(this.parentApplication),_popup_gridb,false));
//PopUpManager.createPopUp(Application.application as
Sprite,_popup_gridb,false));
//PopUpManager.createPopUp(this,_popup_gridb,false));
pop1.showCloseButton=true;
pop1.id = "_pu" + Math.random();
//pop1.dataView = dv;
pop1.title = pop1.id.toString();
PopUpManager.centerPopUp(pop1);
//removeEventListener(MouseEvent.ROLL_OVER,_mOver);
private function _mOut():void{
PopUpManager.removePopUp(pop1);
//addEventListener(MouseEvent.ROLL_OVER, _mOver);
]]>
</mx:Script>
</mx:Text>
Currently, the popup is just a titlewindow w/a datagrid
inside.
thx
