Can't change state with $state.go() neither $location.path() from controller - Ionic

Question

I'm new to Ionic and AngularJS and can't figure out why this does'nt work, i just want to check when on "Home" tab if the user has already entered its card number, if not, redirect him to the appropriate page Here's my controller:

.controller('HomeCtrl', function($scope, $state) {
    if (localStorage.getItem("cardId") == "")
      {
        console.log("redirecting to login");
        $state.go('tab.dash');
      }
})

$state.go seems to do nothing but the console log is properly displayed. I tried with $timeout and $location.path without success.

Here are my routes :

  $stateProvider

    .state('tab', {
    url: '/tab',
    abstract: true,
    templateUrl: 'templates/tabs.html'
  })

    .state('tab.home', {
    url: '/home',
    views: {
      'tab-home': {
        templateUrl: 'templates/tab-home.html',
        controller: 'HomeCtrl',
      }
    }
  })

  .state('tab.dash', {
    url: '/dash',
    views: {
      'tab-dash': {
        templateUrl: 'templates/tab-dash.html',
        controller: 'DashCtrl',
      }
    }
  })

  .state('tab.map', {
      url: '/map',
      views: {
        'tab-map': {
          templateUrl: 'templates/tab-map.html',
          controller: 'MapCtrl'
        }
      }
    })

  .state('tab.account', {
    url: '/account',
    views: {
      'tab-account': {
        templateUrl: 'templates/tab-account.html',
        controller: 'AccountCtrl'
      }
    }
  });

      $urlRouterProvider.otherwise('/tab/home');
});

What I am doing wrong ? I just want to change the state...

Thanks :)
