C# MVC控制器不会创建记录

当我尝试用create操作创建一个新记录时，它失败了，但没有错误，只是不存在。我不太清楚为什么没有或者为什么没有错误。我使用搜索操作填充创建操作中的一些字段，然后填充其余信息

[HttpPost]
    public ActionResult Create(Incident incident)
    {
        if (ModelState.IsValid)
        {
            db.Incidents.AddObject(incident);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.IncidentCreatedBy = new SelectList(db.Creators, "CreatorID", "CreatorName", incident.IncidentCreatedBy);
        ViewBag.ErrorType = new SelectList(db.Errors, "ErrorID", "ErrorDescription", incident.ErrorType);
        ViewBag.IncidentID = new SelectList(db.IncidentItems, "IncidentID", "IncidentItem1", incident.IncidentID);
        ViewBag.IncidentReasonID = new SelectList(db.IncidentReasons, "IncidentReasonID", "ReasonDescription", incident.IncidentReasonID);
        ViewBag.IncidentResolutionID = new SelectList(db.IncidentResolutions, "IncidentResolutionID", "ResolutionDescription", incident.IncidentResolutionID);
        ViewBag.InventoryStatus = new SelectList(db.InventoryStatus, "InvStatusID", "InvStatusValue", incident.InventoryStatus);
        ViewBag.ShipperID = new SelectList(db.ShipperIDs, "ShipperID1", "ShipperName", incident.ShipperID);
        return View(incident);
    }

public ActionResult Search(string searchString)
    {
        Incident i = new Incident();

        if (!String.IsNullOrEmpty(searchString))
        {
            Tracking result = db1.Trackings.FirstOrDefault(r => r.OrderNum == searchString);
            if (result == null)
            {
                return View();
            }
            else

                i.Name = result.Name;
                i.OrderID = result.OrderNum;
                i.IncidentReasonID = 1;

                ViewBag.IncidentCreatedBy = new SelectList(db.Creators, "CreatorID", "CreatorName", i.IncidentCreatedBy);
