Hi,

Thanks for the pull request. However, this functionality is already possible - see the demo: http://plnkr.co/edit/Wtkv71LIqUR4OhzhgpqL?p=preview
You'll notice that the demo uses this expression: meal in meals | filter:q | itemsPerPage: pageSize, where pageSize is a property defined on the scope.

Is there a case where your change enables additional functionality than is already possible?

[brunoporto]

yes already possible, but if you try to remote resources it does not reload new items.

Example:
App load 5 items from the server (pageSize = 5)
Try changing pageSize to 10, will see that app dont load more items.

my change only force reload on current page.

Ok, thanks for the clarification. I'll look into it after the weekend - make sure it works with all the tests etc.
