dhtmlxgrid sortRows() not setting / displaying sort image

grid.parse(data,"json"); grid.sortRows(2,"date","asc");
Why does this not set the sort arrow image in the header of the column? How do I get the image to appear? You would think since I’m calling sortRows() that it would handle the image automatically.

You need to set the sorting image state manually:
