I have a controller that listens on $scope.$on, which will show a popup window when triggered. It works 100% of the time from a couple other controllers' $rootScope.$broadcast methods. But one of them won't work ever.
The controller gets the event, and sets the $scope variable needed, but the page doesn't update, even if I fire $scope.$eval(). Then, if I go to another route, the $scope will finally render, and the modal will pop up on top of that route. I can't tell if I've found a bug in angularjs, or I'm missing something fundamental.

The $scope in an AngularJS is a built-in object, which contains application data and methods. You can create properties to a $scope object inside a controller function and assign a value or function to it. The $scope is glue between a controller and view (HTML).
$scope is a child object that is used to bind the HTML(view) & Javascript(Controller) in a webpage. It is created with the ng-app directive. It is created with the ng-controller directive. It is available globally for all the controllers, i.e, the property assigned with “$rootscope” can be used anywhere.
"How does this and $scope work in AngularJS controllers?" When the controller constructor function is called, this is the controller. When a function defined on a $scope object is called, this is the "scope in effect when the function was called". This may (or may not!) be the $scope that the function is defined on.
scope(); $('#elementId'). scope(). $apply(); Another easy way to access a DOM element from the console (as jm mentioned) is to click on it in the 'elements' tab, and it automatically gets stored as $0 .
You are probably changing the $scope outside of the angular $digest(). Try replacing code making changes with $scope.$apply(function(){ code making changes }). With this the dirty-check should run and update all.

I would recommend using:
$scope.$evalAsync(function() { // scope changes here });
This way you won't run into problems like trying to call apply when there's a digest already in progress.
