Wow wow wow, why do you have a controller only for a checkbox in the first place ? — Alburkerk

What are you trying to achieve ? It's not maybe the good solution — Dan M. CISSOKHO

@Alburkerk covered it pretty well in his answer, so I just have a side note: Using success and error on the $http service is deprecated since they don't return a promise and thus doesn't chain. Use then instead. — Nikolaj Dam Larsen

I think you need to learn more about Angular structure first..

Take a look at John Papa guidelines (easy to find), to learn what should be a controller or not.

Controller are made to be associated with a view / state, ie a big component. So it is very unlikely to be associated with only a checkbox (because it's only a boolean after all).

It you only need to call an http request from multiple endpoints, take a look at what services or factory are for. Just define your http request in a factory, and call it from multiple controllers.

If you really need to spend messages between different controllers, which is unlikely to be the case with your description of your problem, you can use $scope documentation and search about $scope.emit, $scope.broadcast etc..

Here's an example of their use. But as I said, learn more first.
