You could pass events from one controller to another in order to achieve this. You would then do something like:

var app = angular.module('myApp', []);

app.controller('firstController', ['$scope', '$rootScope',
  function($scope, $rootScope) {

    $scope.text = 'Initial text';
    $scope.changeText = function(message) {
      $scope.text = message;
    };

    $rootScope.$on('customEvent', function(event, message) {
      $scope.changeText(message);
    });

  }
]);

app.controller('secondController', ['$scope',
  function($scope) {

    $scope.message = 'Message from second controller';

    $scope.sendEvent = function() {
      $scope.$emit('customEvent', $scope.message)
    };

  }
]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="firstController">
    <h2>This is the fist controller:</h2>
    <p>{{text}}</p>
  </div>
  <div ng-controller="secondController">
    <h2>This is the second controller:</h2>
    <input type="text" ng-model="message" />
    <br>
    <button ng-click="sendEvent()">Send message</button>
  </div>

</div>

Here, the firstController listens to events propagated to the $rootScope, and the secondController sends the message. That is the functionality that you are looking for.

That being said, you would be much better off implementing shared behaviour in a service, since keeping track of all your custom events can be particularly tough.

Hope this helps.
