QTableView connected with QSqlTableModel flickers (scrolls to the bottom and returns)

Hello everyone I have a problem using table view. I have a tableview connected with a QSqlTableModel. On its 2nd column I want to have check state to control the row's Status (active/inactive) but when I try to push the check box QTableView scrolls to the bottom and returns to it's previous position. Is there any solution?
