Timeshechelor not saving to the database record

Question

Hi Team

 

My time schedulor is not saving to the database record, its only creating the events only when a user creates them. Need some help as to why, even if i refresh the browser those events are not being saved.

public ActionResult eNtsaCourseEvents()
       {
           RegCoursesViewModel regCourses = new RegCoursesViewModel();
           var sched = new DHXScheduler(this);
           sched.Skin = DHXScheduler.Skins.Terrace;
           sched.LoadData = true;
           sched.EnableDataprocessor = true;
           sched.InitialDate = new DateTime(2020, 09, 17);
           return View(sched);
       }

       //GET:Data-Calendar.
       public ContentResult eNtsaData()
       {
           return (new SchedulerAjaxData(
              new eNtsaRegistration_2().Events
              .Select(e => new { e.id, e.text, e.start_date, e.end_date })
              )
              );
       }

       // Save-Data-Events.
       public ContentResult eNtsaSaveEvents(int? id, FormCollection actionValues)
       {
           var action = new DataAction(actionValues);
           var changedEvent = DHXEventsHelper.Bind<eNtsaCalendarEvents>(actionValues);
           var entities = new eNtsaRegistration_2();

           try
           {
               switch (action.Type)
               {
                   case DataActionTypes.Insert:
                       entities.Events.Add(changedEvent);
                       break;
                   case DataActionTypes.Delete:
                       changedEvent = entities.Events.FirstOrDefault(ev => ev.id == action.SourceId);
                       entities.Events.Remove(changedEvent);
                       break;
                   default:// "update"
                       var target = entities.Events.Single(e => e.id == changedEvent.id);
                       DHXEventsHelper.Update(target, changedEvent, new List<string> { "id" });
                       break;
               }
               entities.SaveChanges();
               action.TargetId = changedEvent.id;

           }
           catch (Exception e)
           {
               action.Type = DataActionTypes.Error;
           }
           return (new AjaxSaveResponse(action));

       }
