MVC完整日历错误

Question

当我运行我的日历时，我收到了这个错误...我已经在另一个日历中使用了这些方法与另一个表...并且它有效。 ObjectContext实例已被删除，不能再用于需要连接 ...引用GetEvents方法的操作。

模型

public partial class Reserva
{
    public int ID_Reserva { get; set; }
    public int ID_Cliente { get; set; }
    public int ID_Quarto { get; set; }
    public System.DateTime DataEntrada { get; set; }
    public Nullable<System.DateTime> DataSaida { get; set; }
    public int NumeroPessoas { get; set; }
    public Nullable<int> NumeroNoites { get; set; }
    public Nullable<decimal> Preço { get; set; }
    public string Observaçoes { get; set; }

    public virtual Cliente Cliente { get; set; }
    public virtual Quarto Quarto { get; set; }
}

控制器

public JsonResult GetEvents()
{
    using (HotelEntities dc = new HotelEntities())
    {
        var events = dc.Reserva.ToList();
        return new JsonResult { Data = events, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
    }
}

 $(document).ready(function () {
            var events = [];
            var selectedEvent = null;
            FetchEventAndRenderCalendar();
