我想让两个火花网格列在复选框单击事件上可编辑。我为此编写了以下代码。但我没有java函数来实现这个。所以任何人都可以帮助我..？

<s:DataGrid id="dataGrid" x="3" y="44" width="792" height="243" editable="true"  fontSize="15"
requestedRowCount="4" dataProvider="{getSalesReturnCgt.lastResult}">
<s:columns>
<s:ArrayList>
<s:GridColumn dataField="selectFlag" rendererIsEditable="true"  headerText="SrNo"      width="60" editable="false">
<s:itemRenderer>
<fx:Component>
<s:GridItemRenderer>
<s:layout>
<s:HorizontalLayout horizontalAlign="center" verticalAlign="middle"/>
</s:layout>
</fx:Script>
<s:Label id="srno" text="{cgtsrobj.sr_no}" />
<s:CheckBox id="chkBox" click="chkBox_clickHandler(event)" />   
</s:GridItemRenderer>
</fx:Component>
</s:itemRenderer>
</s:GridColumn>
<s:GridColumn dataField="lot_Id" headerText="Item"></s:GridColumn>

First of all, you dont need java code for this, now to achieve this, write the chkBox_clickHandler function, from there you should dispatch an event which you should handle in GridItemEditor
