How to access another scope with controller?

Question

I know that you can create binding with a directive but is it possible with a controller? Maybe this is stupidly simple but I couldn't figure out.

For example I would like to click on a text in x scope's view and execute a function in another scope.

function firstCtrl() {
    var vm = this;
    vm.data = 'First scope stuff!';
}

function secondCtrl() {
    var vm = this;
    vm.data = 'Second scope stuff!';
  }

  vm.clicked = function() {
    alert('firstScope is clicked!'); 
  };

Here is what I have: http://plnkr.co/edit/CpPKsEGPZWzufB2K1FK3

Is there a reason that the function can't be in a service instead of the controller? — Scottie, Apr 20 '15 at 17:57

@KrzysztofSafjanowski maybe.. I would like to know the answer though. But I have just read the answer of the questions 'http://stackoverflow.com/questions/25417162/how-do-i-inject-a-controller-into-another-controller-in-angularjs' and that explains to me. — Mar, Apr 20 '15 at 18:04
what u want in your plunk is just impossible -- if I click on first href - second controller is not initialized, so ofc I cant use his methods. — Petr Averyanov, Apr 20 '15 at 18:53

There are multiple ways how to communicate between controllers. One way is emitting an event on scope:

function FirstCtrl($scope) 
{
  $scope.$on('someEvent', function(event, args) {});
  // another controller or even directive
}

function SecondCtrl($scope) 
{
  $scope.$emit('someEvent', args);
}

Another way sharing a service.

Hope it helps. Also check this https://stackoverflow.com/a/9407953/4782034

$emit is rare case to use it, if controller hierarchy is there – Pankaj Parkar Apr 20 '15 at 18:15
