Chances are that if you're using Entity framework, you view (what ever it is, HTML web page or a Web Form) is already bound to your model... Entity framework uses a model to fetch data or to perform different CRUD operations. The list that you're watching; after querying the database is a result of the CRUD operation of Entity framework over model.

If you're going to use Entity framework for all of your operations, create, read, update and delete, then yes your model will be bound to your application's views for operations. It is up to you, how you define "model binding". By the way, there is nothing compulsory in programming. It is just a requirement of your programming model; paradigm. So, which so ever pattern you're using, read about it and you will find the answer about it more explicitly there.

C#

[WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public string GetSubCategories(int CategoryId)
        {

            DataTable dt = BusinessLayer.ycfoCore.populateSubCategories(CategoryId.ToString());

            var query = from row in dt.AsEnumerable()
                        select new
                        {
                            Id = row["Id"].ToString(),
                            Name = (string)row["Name"]
                        };

            JObject o = JObject.FromObject(new
            {
                Table = query
            });

            return o.ToString();
        }
