I have a parent child controller example above, in the child when a button is clicked I displays the div showPop and then will $emit an event upwards to the $rootScope.
Now in the parent / $rootScope I "hear" that event then activate another function.
That function in the $rootScope triggers the bodyClick click function to be active, so once a click is registered in the body/parent/rootScope the div showPop is now hidden.
The problem is that while I want clicks on the body to close that div out, I do NOT want clicks on the actual div itself to trigger it to close?
How could I accomplish this / work around the $rootScope ng-click event?
.controller('mainController', ['$scope', '$rootScope',
                              function($scope,$rootScope) {
  var unbind = $rootScope.$on('popoverOpen');
  $scope.$on('popoverOpen', function(events, data) {
    console.log('popoverOpen is heard!')
    $scope.bodyClick = function() {
        console.log('bodyClick sent down from main');
        $scope.theAction = 'bodyClick sent down from main';
        $rootScope.$broadcast('bodyClick');
    };
    $scope.$on('$destroy', unbind);
  });
}])
.controller('subController', ['$scope', '$rootScope',
                             function($scope, $rootScope) {
  $scope.callPop = function($event) {
    $rootScope.theAction = 'popoverOpen emitted up from sub';
    $event.stopPropagation();
    $scope.showPop = true;
    $scope.$emit('popoverOpen');
  };
  $scope.$on('bodyClick', function() {
    console.log('bodyClick received in sub!');
    $rootScope.theAction = 'bodyClick received in sub!';
    $scope.showPop = false;
    $scope.$emit('destroy');
  });
}]);
Markup:
<body ng-app="app" ng-controller="mainController" ng-click="bodyClick()">
<h1>mainController</h1>
<div class="sidebar" ng-controller="subController">
  <h2>subController</h2>
  <button ng-click="callPop($event)">Click Me</button>
  <div ng-show="showPop" class="pop-box">This is showPop, clicking in here should not close it, clicking outside should!</div>
</div>
<section class="the-section">
  {{theAction}}
</section>
</body>
