Listening for dataChange event in AdvancedDataGrid - flex4

Question

This is my code:
<controls:AdvancedDataGrid id="adg" dataChange="adg_dataChangeHandler(event)">
<!-- other stuff goes here -->
</controls:AdvancedDataGrid>
and in my ActionScript code:
protected function adg_dataChangeHandler(event:FlexEvent):void
{
trace(1);
}
When I edit a cell in advancedDataGrid (making the columns editable of course) it never dispatches an event. Or, in other words, my function is never called. How can I fix this?

Answer 1

I think that the better option for my scenario is to use an itemEditor, that has a listener put on the change event. Code looks like :
<controls:AdvancedDataGrid id="adg">
<controls:groupedColumns>
<adgs:AdvancedDataGridColumn headerText="A" wordWrap="true" dataField="name" editable="false" itemEditor="Aaa"/>
</controls:groupedColumns>
</controls:AdvancedDataGrid>
and the item editor class is here :
<?xml version="1.0" encoding="utf-8"?>
<mx:TextInput xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" change="textinput1_changeHandler(event)" restrict="0-9">
<fx:Script>
<![CDATA[
protected function textinput1_changeHandler(event:Event):void
{
trace("ha");
}
]]>
</fx:Script>
</mx:TextInput>
