mvc bootstrap modal save not working

Question

Hi Team

 

I have problem, my modal to create is not saving to my database table. Here is my logic;

[Route("Home/CoursesRegistration")]
public ActionResult CoursesRegistration(eNtsaRegCourses model) {
  if (ModelState.IsValid) {
    ViewBag.Message = "Course created";
    ModelState.Clear();
    cb.SaveChanges();
    return PartialView("CoursesRegistration", "Home");
  }

  return View("eNtsaCourses", model);
}

//GET://Courses/Courses-All.
[Route("Home/Courses")]
public ActionResult Courses(eNtsaCourses courses) {
  if (ModelState.IsValid) {
    var data = cb.eNtsaCourse.Add(courses);
  }
  return View(courses);
}
// db-schema lists.
public class eNtsaCourses
{
    [Key]
    public Guid? Id { get; set; }
    public string Course { get; set; }
    public string Nickname { get; set; }
    public string Term { get; set; }
    public string EnrolledAs { get; set; }
    public bool Published { get; set; }
}
