GridColumn and dataProvider update

[pol2095]

Hello,

in a Spark GridColumn, how to detect if the DataGrid.dataProvider has been
updated ?

/<s:DataGrid id="dg" x="100" y="48" selectionMode="multipleRows"
requestedRowCount="4">
        <s:columns>
                <s:ArrayList>
                        <s:GridColumn dataField="myBoolean">
                                <s:itemRenderer>
                                        <fx:Component>
                                                <s:GridItemRenderer>
                                                        <fx:Script>
                                                                
                                                        </fx:Script>
                                                        <s:CheckBox id="cb" 
label="" horizontalCenter="0"
change="data.myBoolean=cb.selected;"/>
                                                </s:GridItemRenderer>
                                        </fx:Component>
                                </s:itemRenderer>
                        </s:GridColumn>
                <s:GridColumn dataField="dataField1" headerText="Column
1"></s:GridColumn>
                <s:GridColumn dataField="dataField2" headerText="Column
2"></s:GridColumn>
                <s:GridColumn dataField="dataField3" headerText="Column
3"></s:GridColumn>
                </s:ArrayList>
        </s:columns>
        <s:typicalItem>
                <fx:Object dataField1="Sample Data" dataField2="Sample Data"
dataField3="Sample Data"></fx:Object>
        </s:typicalItem>
        <s:ArrayCollection>
                <fx:Object dataField1="data1" dataField2="data1"
dataField3="data1"></fx:Object>
                <fx:Object dataField1="data2" dataField2="data2"
dataField3="data2"></fx:Object>
                <fx:Object dataField1="data3" dataField2="data3"
dataField3="data3"></fx:Object>
                <fx:Object dataField1="data4" dataField2="data4"
dataField3="data4"></fx:Object>
        </s:ArrayCollection>
</s:DataGrid>/
