function dataBound(e){
var items = grid.items();
items.each(function (index) {
var dataItem = grid.dataItem(this);
 if (dataItem) {
      if (dataItem["ActionTaken"] == "Add"){ 
        if (rowChanges[dataItem.id]) {
            for (key in rowChanges[dataItem.id]) {
                 dataItem.set(key, rowChanges[dataItem.id][key]);
            }

          }
      }
    }    
  }
