I want to show table data using Ajax in Asp.Net MVC. What is wrong with this Ajax syntax?

Question

I want to show table data using Ajax request.

Here is my Ajax Syntax:

  $(document).ready(function() {
                var table = $("#attendance").DataTable({
                    ajax: {
                        url: '@Url.Action("GetAttendance", new {id = Model.Student.Id})',
                        dataSrc: ""
                    },
                    columns: [
                        {
                            data: "Date",
                            render: function(data) {
                                return data;
                            }
                        },
                        {
                            data: "Status.StudentStatus",
                            render: function(data) {
                                return data;
                            }

                        }
                    ]
                });

Here is my action method:

  public JsonResult GetAttendance(int id)
    {
        var studentAttendance = _context.Attendances.ToList().Where(m => m.StudentId == id);
        return Json(studentAttendance, JsonRequestBehavior.AllowGet);
    }

Now, where am I wrong?

Please plug in the following example. If you don't mind, please just follow my example, and then you will be able to fix your issue.

Controller/Model:

public class AjaxViewModel
{
    public string theDate { get; set; }
    public string StudentStatue { get; set; }
}

public class HomeController : Controller
{
    public string GetAttendance()
    {
        AjaxViewModel aViewModel = new AjaxViewModel { StudentStatue = "stat4", theDate = "12/24/2005" };
        AjaxViewModel aViewModel2 = new AjaxViewModel { StudentStatue = "stat5", theDate = "12/24/2005" };
        AjaxViewModel aViewModel3 = new AjaxViewModel { StudentStatue = "stat6", theDate = "12/24/2005" };

        IList<AjaxViewModel> data = new List<AjaxViewModel>();
        data.Add(aViewModel);
        data.Add(aViewModel2);
        data.Add(aViewModel3);

        JavaScriptSerializer js = new JavaScriptSerializer();
        string json = js.Serialize(data);
        json = "{ \"data\": " + json;
        json = json + " }";
        return json;
    }
