RadClientDataSource does not update the data properly when bound to EntityDataSource. The proper data is displayed only of first load (when the data is fetched via _kendoDataSource.read()), but not after an update (e.g. a page change)

Steps to reproduce:

1. Open https://demos.telerik.com/aspnet-ajax/clientdatasource/functionality/binding-to-datasourcecontrols/defaultcs.aspx
2. Do either one of the following
    - Change to page 2 and go back to page 1
    - Hitting refresh loses all data
    - Edit multiple values before saving -> many of them are lost
    - Upon save, the old data reappears before being updated.

Result - the Grid is not bound with the correct data
