How to make Angular remove all socket.io listener's only on controller reload?

Question

Angular

Tell me, maybe there is some kind of event, like "controller reload" or something similar.

.controller('chatNotificationCtrl', ['$scope', 'socket', 'toastr', '$rootScope', '$state', function($scope, socket, toastr, $rootScope, $state) {
  alert('REFRESHED')
  $scope.chatNotifications = {};
  console.log('STARTED NOTIFICATION CONTROLLER');
  if ($scope.logged) {
    $scope.chatNotifications = $scope.logged.chatNotify;
  } else {
    return;
  }
  socket.on('notify:chat', function(data) {
    console.log('NOTIFY CHAT');
    $scope.chatNotifications.unshift(data);
    toastr.success('Example', 'New Message');
  });

  $rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams) {
    socket.getSocket().removeAllListeners();
  })

}])

I have done so for now, but if the state changes, this does not mean that the controller always restarts, there are nested routes just ..
