AngularJS, Populating dependent Combobox

Question

What I am trying to achieve is to populate a child combobox with items which depend on a \'parent\' combobox.

To clarify the - or better my - problem, I have created

Answer 1

There is other solution to this kind of issues. That is to broadcast.

Do brodcast after you got the data. In this example data came from Ajax call.

$http.get('/SampleProgram/get_all_users').success(function(rsList){
       $scope.users =  rsList;
       $scope.$broadcast('I got all the users');
    });

There should be listeners who always keeps their ears up for your broadcast message.

$scope.$on('I got all the users', function () {
        alert("Hey All the users are here already let's make another ajax call with those users");
    })
