Get ClientDataKeyName from hiecry grid in javascrtip

[Eric Klein]

I have a grid that is a hieracry and uses a panel to load the child

        </Columns>
     </mastertableview>
     <pagerstyle alwaysvisible="true" />
   </telerik:RadGrid>
 </asp:Panel>

as you can see I hae a combo box in the child panel that when changed in the grid I want to run an update fo rthe data.

function UpdateDocument(sender, args) {
               var item = args.get_item();
                     Compliance.DocumentLogWS.UpdateDocument(sender.get_errorMessage(), sender.get_value(), DocumentUpdater);
           }

this works when the grid is jut on layer, but when I am running from the child panel the sender.get_errorMessage() gives me a callback error.  How can I get the the Clientdatakeynames="DocumentLogID" for the row the the combox has been changed.
