Two things:
First you assign a new action to previousItem and nextItem. Therefore you loose 
the pointer to the original one. This wouldn't cause functional problems, but 
is not really transparent and it is unnecessary.
Secondly I have a running merge request, where I change all those code lines. 
So the easiest would be to integrate it in my code as I have to write it anyhow 
once again.
