$scope.tabContainer is null

[omril1]

Sometimes the $scope.init function runs before the uib-tabset directive finished rendering into the DOM, so the querySelector returns null.
$el[0].querySelector('.spacer ul.nav-tabs');

I temporarily fixed it in my code by setting in a delay for the init function.
ex:

$timeout(function(){
     $scope.init();
 }, 100);

Is there a better solution?
