How can I prevent grid to get all data in grid when insert data the second time?

[CHIHPEI]

Question

I had a grid with EditMode of  "GridEditMode.InCell".

Users can insert multiple data by Datasource  ajax create method.

The create method works fine the first time.

However, when I tried to insert data the second time

The action recieved all of the data from view(includes the data already inserted in the first time).

How I can prevent from getting datas already inserted?

Is there any work arrounds?
