Pass a value to an item renderer button

Question

I have a datagrid.  One of the columns has a value of "@recipe", with is a string that's a URL.
I need to replace this with a link button that goes to this url.
So I created an Item Renderer:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private var linkToGoTo:String = XML(data).@recipe
          private function goRecipe(event:MouseEvent):void {
          trace("Link="+linkToGoTo);
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="Related Recipe" click="goRecipe(event)" />
</mx:Canvas>
Problem is that I am not getting my XML value.   If I did this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private function goRecipe(event:MouseEvent):void {
          trace(event.currentTarget.label);
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="{XML(data).@recipe}" click="goRecipe(event)" />
</mx:Canvas>
This works, but of course I do not want the label to be this long URL.  How would I do this?

OK, I got it to work like this, not sure if it's the best way:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private var relatedRecipe:String
          override public function set data(value:Object):void
        if(value != null)
           super.data = value;
           relatedRecipe = value.@recipe
           if (relatedRecipe.length>1) {
                trace("recipe="+relatedRecipe);
                related.visible = true;
           } else {
                related.visible = false;
        private function goRecipe(event:MouseEvent):void {
             var linkToGoTo:URLRequest = new URLRequest(relatedRecipe);
             navigateToURL(linkToGoTo, "_blank");
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="Related Recipe" click="goRecipe(event)" textDecoration="underline" fontSize="10" styleName="recipeLinkButton" />
</mx:Canvas>
