DataTables Editor with previous / next buttons + fnFilter

I would like to use Previous/Next buttons on the Editor but I also use fnFilter to limit the number of rows to display.
Unfortunately, with the Previous/Next I jump to the next in the database without any consideration to the fnFilter.
Could you tell me if I have to add this fnFilter somewhere else in aButtons or if this is just a bug ?
