when you set is for a column, it will show a checkbox in the header, and onSelectedRowsChanged will be called whenever it is clicked, with: isgroupselection= true (it is a group selection), groupcolumnid = id_of_column, groupkey = null (because this handler is also used for selection groups, in which case it is the group name), groupselection = true/false based on the check state; you need to actually select the rows in the model when this handler is called;
