I have been working around onsen-ui recently and got stuck when I was trying to reference a Carrousel var (var="carousel") within a Tabbar and Navigator components.
The code works until I try to use Tabs. I get the following error:
Uncaught (in promise) TypeError: Cannot read property of undefined
I have tired the ‘pageinit’ solution but it doesn’t seem to work.
Here under the HTML.

</div>
</ons-carousel-cover>
</ons-carousel>
</ons-page>
</ons-navigator>
</ons-template>
</body>
</html>
And app.js
var module = ons.bootstrap('my-app', ['onsen']);
module.controller('AppCtrl',['$scope', function($scope) {
}]);
module.controller('carouselCtrl',['$scope', function($scope) {
ons.ready(function() {
$scope.iconIndex = $scope.carousel._attrs.$$element[0].children[$scope.carousel.getActiveIndex()].id;
$scope.$apply();
$scope.carousel.on('postchange', function (event) {
$scope.iconIndex = $scope.carousel._attrs.$$element[0].children[$scope.carousel.getActiveIndex()].id;
$scope.$apply()
});
});
}]);
Do you have any idea where the issue comes from?
Many thanks for your time.
