如何在不刷新的情况下更新Kendo网格聚合

I am working on a kendo grid with remote data, and currently when updating my grid, I use the dataItem.set() method to manually sync the grid with the data. This works fine, but unfortunately the aggregates in the footer are not refreshed. They refresh only when calling dataSource.fetch(), which hangs up the application for about 10 seconds. The users however, would like more excel-like responsiveness where every change they make is immediately reflected in the total, but also persisted to the database. Is this possible using the kendo api? Or do I have to do this manually with jQuery?I am working on a kendo grid with remote data,
