Sorry, but this is wrong.

You need to return 'undefined' in case there are no changes, this patch just
fires the question dialog everytime.

See this page for more:

We could also consider to add this functionality to all Koha pages (or almost
all) through some existing plugin like http://plugins.jquery.com/are-you-sure/
but thats definitely out of scope of this bug, as Rancor is a special case.
