AngularJs & Ionic : Stop/Restart $timeout when change and return to view

Question

I have a View that is updated after 1 minute, I stop the timer after before leaving this view, and all is OK. After returning to the current view the timer don't restart again.

This is the code of the controller of this view:

.controller('IndexCtrl', function($scope, $timeout, RestService) {
    var updateN = 60*1000;
    $scope.test = "View 1 - Update";
    var update = function update() {
         timer = $timeout(update, updateN);
         /** make a http call to Rest API service and get data **/
        RestService.getdata(function(data) {;
             $scope.items = data.slice(0,2);
         });
    }();

   /** Stop the timer before leave the view**/
    $scope.$on('$ionicView.beforeLeave', function(){
   $timeout.cancel(timer);
      //alert("Before Leave");
   });  

   /** Restart timer **/
    $scope.$on('$ionicView.enter', function(){
    $timeout(update, updateN);
      //alert("Enter");
   }); 
})

.controller('ViewCtrl2', function($scope) {

  $scope.test = "View 2";

});

I resolve the problem, There is not a problem with the cache, but with the function update that is not called after I re-enter on the page. I move the update function inside the $ionicView.enter : The corrected code is:

   $scope.$on('$ionicView.beforeLeave', function(){
      //updateN=12000000;
      $timeout.cancel(timer);
      //alert("Leave");
   });

  $scope.$on('$ionicView.enter', function(){
      //updateN=12000000;
    var update = function update() {
    timer = $timeout(update, updateN);
    RestService.getdata(function(data) {
        //console.log(tani);
        //$scope.items = data;
        $scope.items = data.slice(0,2);
    });
   }();
   });
