title: Directive rendered via UI-Grid cellTemplate rendering incorrectly
body: <p>I am experiencing a strange issue in that my directive seems to be executing on stale row.entities, meaning it does not get the new values as you scroll down or modify the sort of the grid.  The initial ~20 rows render fine but past that the directives become disassociated with the rows.</p>
