Bind a collection to a model in Backbone
===

I have a server side class:`TopicsListModel`
with properties as follows:

    public class TopicsListModel
    {
        public TopicsListModel()
        {
            ChildTopics = new HashSet<TopicsListModel>();
        }

        public int Id { get; set; }
        public string Name { get; set; }
        public ICollection<TopicsListModel> ChildTopics { get; set; }
    }
There is a function which returns a List<TopicsModel>,

    public JsonResult SearchTopic(String topic)
        {
            var topics = LandingManager.SearchTopics(topic);
            //return Json(topics);
            return new JsonResult { Data = topic, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
        }


 I need to add this to the Backbone model and collection. I am a newbie to Backbone and I am struggling as you can guess. Any help would be greatly appreciated.
