Angular: How to force recompile directive?

问题

HTML:

<div ng-repeat="obj in arr">
   <custom-directive status-stored-in="obj"></custom-directive>
</div>

Problem:

I have page-turn built in for the large amount of objs. Which means that the value of arr, representing the current page of objs, will change. However, the obj in the status-stored-in="obj" part is not refreshed with the change.

Right now my solution is to add a ng-if in customDirective, flickering its value back and forth to have it force recompiled. Is there any other equivalent, neater way to deal with this?

Edit:

The start of the custom directive:

module.directive 'checkbox', (checkboxHooks) ->
  restrict: 'E'
  scope:
    hook: '='
    hookedTo: '='
    statusStoredIn: '='
  templateUrl: 'templates/checkbox.html'
  link: (scope, element, attr) ->

The gist is that it needs to get hold of an object, for storing the checked status. The whole of it can be found here: [coffee/js].

回答1:

Inside your directives link function you need to watch status-stored-in for changes and then recompile it e.g.:

   link: function(scope, element) {
    scope.$watch('statusStoredIn', function() {
      element.html(statusStoredIn);
      $compile(element.contents())(scope);
    });
   }
