Get row id from selected bwu_data_grid row

Question

I subscribe on bwu click event:

grid.onBwuClick.listen((e) {
  int id = grid.dataProvider.items[e.cell.row]['id'];
});

And I have pagination for table. When clicked row on first page I get right row id. But on other pages I get id of row from first page.

I expected 768 and 769 ids.

Should I do something when page changed?
