Re: Update method not working ??

why dont you just check what is coming back from service

1. oModel.getModel().update("/es_koldb('" + vKolId + "')",oEntry,null,function(oData, oResponse){ 
2.               jQuery.sap.require("sap.m.MessageToast"); 
3.               sap.m.MessageToast.show("Data Updating Succesfully"); 
4.              },function(oError){ 
5.                alert("update failed: " + JSON.stringify(oError) ); 
6.              }); 

and as suggested - set a breakpoint in *DPC_EXT
