Accessing DataGrid currentTarget from a dataGridColumn button

Question

I am trying to access the row item clicked from within a datagrib button. Any thoughts? It seems to only accept event or mouseevent...
               public function onDeleteItem(e:Event):void{
                    trace(e.currentTarget.parent);     
<mx:DataGridColumn headerText="Remove" width="60">
                              <mx:itemRenderer>
                                   <mx:Component>
                                         <mx:Box horizontalAlign="center" verticalAlign="middle">     
                                              <mx:Button skin="@Embed('assets/remove_icon.png')"
                                                   buttonMode="true" scaleX=".6" scaleY=".6" click="outerDocument.onDeleteItem(event)" />           
                                         </mx:Box>
                                   </mx:Component>
                              </mx:itemRenderer>
                         </mx:DataGridColumn>

You need to access the dataProvider using the DataGrid selectedItem property.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
  <mx:Script>
    <![CDATA[
      import mx.collections.ArrayCollection;
      [Bindable] private var ac:ArrayCollection = new ArrayCollection([
        {test: "one"}, {test: "two"}, {test: "three"}, {test: "four"}, {test: "five"}
      public function clickFunc():void{
        txt.text = dg.selectedItem.test;
    ]]>
  </mx:Script>
  <mx:DataGrid id="dg" dataProvider="{ac}">
    <mx:columns>
      <mx:DataGridColumn dataField="test">
        <mx:itemRenderer>
          <mx:Component>
            <mx:Button label="Click Me" click="outerDocument.clickFunc();"/>
          </mx:Component>
        </mx:itemRenderer>
      </mx:DataGridColumn>
    </mx:columns>
  </mx:DataGrid>
  <mx:Text id="txt"/>
</mx:Application>
