Correct use for angular-translate in controllers

Question

I\'m using angular-translate for i18n in an AngularJS application.

For every application view, there is a dedicated controller. In the controllers below, I set the v

To make a translation in the controller you could use $translate service:

$translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
    vm.si = translations['COMMON.SI'];
    vm.no = translations['COMMON.NO'];
});

That statement only does the translation on controller activation but it doesn't detect the runtime change in language. In order to achieve that behavior, you could listen the $rootScope event: $translateChangeSuccess and do the same translation there:

    $rootScope.$on('$translateChangeSuccess', function () {
        $translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
            vm.si = translations['COMMON.SI'];
            vm.no = translations['COMMON.NO'];
        });
    });

Of course, you could encapsulate the $translateservice in a method and call it in the controller and in the $translateChangeSucesslistener.
