I have set the data processor enabledegug to true inorder to check the values which are being sent to the server. I see that whenever an update operation is being performed the !nativeeditor_status is empty. How can i set the !nativeeditor_status to updated when an update operation occurs?

!nativeeditor_status can have next values
inserted - for new rows
deleted - for deleted rows
update or empty - for updated rows

You can set any custom value by setting userdata for related row
