Telerik Radgrid Issue in Modal box ASP.Net Webforms

I am using Telerik Ragdrid in the Modal Box but it is not fetching any values on OnBatchEditCommand in the Radgrid that I populated from jquery.

Here's the code from which I populated the Radgrid

var tableView = $find("<%= RadGrid2.ClientID %>").get_masterTableView();
tableView.set_dataSource(data);
tableView.dataBind();

The code where I am not getting values

 protected void RadGrid1_BatchEditCommand(object sender, GridBatchEditingEventArgs e)
        {
            foreach (GridBatchEditingCommand command in e.Commands)
            {
                Hashtable oldValues = command.OldValues;
                Hashtable newValues = command.NewValues;
}
}
