Not sure what issue you are trying to fix here, but sounds like this PR was inactive for a long time. Reopen if you still need this

Ok, found it. This is supposed to fix #138

This can be closed along with the original issue, the 'working solution" doesn't actually do anything as scope.$apply is a variable referencing a function. This function is never executed since it doesn't get invoked using ()
