Hello, I upgraded the library to version 0.8.9. Something is wrong with click events. The app crashes each time the user clicks the cell / column / row.

If the user clicks the cell:

java.lang.NullPointerException: Attempt to invoke interface method 'void com.evrencoskun.tableview.listener.ITableViewListener.onCellClicked(androidx.recyclerview.widget.RecyclerView$ViewHolder, int, int)' on a null object reference

If the user clicks the column:
