You are changing the DataTable directly and expect DataGridView's event to be fired? I suggest that you change the cell value programatically as:

DataGridView[ColumnIndex, RowIndex].Value = NewValue;

Additionally you will have to Call DataGridView.CommitEdit() to commit the values to the DataTable. This should trigger the CellValueChanged event.
