Java Table Handle for Cell Edit

I am using Java Handle for uitable by declearing as

 jtable = uitable('v0',1,'Parent',f)

In order to check the invalid entry from the user, i need the previous data and new data entered by the user. how to get the revious data for the edited cell. I tried with matlab event.PreviousData for the uitable it is not working.

I declared a function jatble.DataChangedCallback = @myDataChange_Callback.

function myDataChange_Callback(mtable, eventdata)

   eventDetails = eventdata.getEvent;
   modifiedColIdx = eventDetails.getColumn;
   modifiedRowIdx = eventDetails.getFirstRow;
   jtable.getValueAt(modifiedRowIdx,modifiedColIdx);

end

I am able to get new data but old data was lost. Can some one help me.
