Which event is raised after sorting a column

Hi,
I need to update a second control dependend on the order of the rows in the grid.
Im using obj.getRowIndices() to get the order of the rows, but this functions return the right values just after sorting is done.
All events that I've found in the documentation like obj.onHeaderClicked or obj.onHeaderMouseUp are raised before sorting is done.

Can you use onRowIndicesChanged?

obj.onRowIndicesChanged = function(rowIndicesArray){
    alert(rowIndicesArray);
}

works very well, thx
