odata - Kendo UI Grid - Add new record shows 0 as ID -

i'm using kendo ui grid asp.net mvc, entity framework , odata. have record id inside grid - far good.

but when click on "add new record" in toolbar id column shows me 0 while i'm editing data.

and after click on "update" button doesn't change correct id (which has been returned service):

{       "odata.metadata":"http://localhost:61534/api/$metadata#assetlist/@element",     "id":17,     "manufacturername":"test",     "name":"test",     "serialnumber":"test",     "assetstateid":1,     "assetstatename":"test",     "nextcalibration":"2013-07-11t09:08:28.298z" } 

when refresh page/browser correct id shown.

here's post method:

public override httpresponsemessage post(assetlistviewmodel item) {     // #### mg: create asset     rsams.webui.models.asset asset = new asset();     asset.manufacturer = item.manufacturername;     asset.name = item.name;     asset.serialnumber = item.serialnumber;     asset.assetstateid = 1; // in use     asset.nextcalibration = item.nextcalibration;     db.asset.add(asset);     db.savechanges();      // #### mg: response     item.id = asset.id;     item.assetstateid = asset.assetstateid;     var response = request.createresponse<assetlistviewmodel>(httpstatuscode.created, item);     response.headers.location = new uri(url.link("odata", new { id = item.id }));     return response; } 

and here's datasource js (part of it):

datasource: { type: "odata", pagesize: 25, serversorting: true, serverpaging: true, transport: {     create: {         url: "/api/assetlist",         datatype: "json"     },     read: {         url: "/api/assetlist",         datatype: "json"     },     update: {         url: "/api/assetlist",         datatype: "json"     },     destroy: {         url: function (data) {             return "/api/assetlist([rw-param])".replace("[rw-param]", data.id);         },         datatype: "json"     } 

the field display "0" text, because default value of "recordid " property (this default behavior). supports setting value after data retrieved.what can clear value manually:

 function ongridedit(e) {          if (e.model.isnew()) {             e.model.set("recordid", null);         } } 

this code needs placed in grid edit event handler.
