title: Working with $scope.$emit and $scope.$on
body: <p>How can I send my <code>$scope</code> object from one controller to another using <code>.$emit</code> and <code>.$on</code> methods?</p>
  
  <pre><code>function firstCtrl($scope) {
      $scope.$emit('someEvent', [1,2,3]);
  }
  
  function secondCtrl($scope) {
      $scope.$on('someEvent', function(mass) { console.log(mass); });
  }
  </code></pre>
  
  <p>It doesn't work the way I think it should. How do <code>$emit</code> and <code>$on</code> work?</p>
