Forcing custom item renders to refresh

I have an AdvancedDataGrid. One of the columns in the grid displayed with help of custom render. During the application run, I set another custom render to the same column. When I scroll data in the grid (change values for the custom render开发者_运维问答s) they display new view correctly.

I want that they dispaly new view automatically (when I set them): so I think I have to call them and tell tham to refresh rgeir views. Any idea how to do this?

Use invalidateList()
