Redefine data packet in Kendo UI grid edit popup

[Rasika]

I think this is an advance topic in Kendo UI. I have a Kendo UI grid and I added a custom edit popup to update the data in the grid.
My data packet like this :

 

{
 fieldOne : "valueOne";
 fieldTwo : "valueTwo";
 fieldThree : [{a : "someValue", b : "someValue"},{a : "someValue", b : "someValue"}]
}

 In edit popup I will edit this data. But I have a new requirement that add a new value to fieldThree. My new Data packet will look like this...     

 {

  fieldOne : "valueOne";

  fieldTwo : "valueTwo";

  fieldThree : [{a : "someValue", b : "someValue"}]

 }

 

 

 

What I have done is I made a custom popup and custom fields for that. But my question is how I redefine the data packet to above one ?? In Kendo UI it will only update existing values...
