In flex 1.5 you will have to do that on "change" event in cellRenderer:
MyCellRenderer.mxml
<mx:HBox>
<mx:Script>
<![CDATA[
<![CDATA[
function updateDP()
{
//loop through the dataProvider for DataGrid and setValues.
parentDocument.MyDataGrid.executeBinding(); //this may not be required, this will re-render the DataGrid
parentDocument.MyDataGrid.executeBinding(); //this may not be required, this will re-render the DataGrid
}
]]>
</mx:Script>
</mx:Script>
<mx:TextInput id="MyTI" change="updateDP()"/>
</mx:HBox>
