insert is called twice update and delete methods are bound to Post in telerik aspnet-core scheduler UI?

[Abdalla]

I am using Telerik UI Scheduler for asp.net core Project.I am using WebApi to bind data and insert new meeting to the room but I have 2 problems are:

 1. insert is called twice when I insert new Item. 
 2. update and delete methods are bound to Post and they are not calling corresponded  do delete of add operation.

html view

    @(Html.Kendo().Scheduler<Meeting>().Name("scheduler").Date(new DateTime(2017, 5, 13))
          .StartTime(new DateTime(2017, 5,13, 7, 00, 00))
          .Editable(true)
          .Views(views=>{
              views.DayView();
              views.AgendaView();
          })
          .Height(600)
          .Timezone("Etc/UTC")
          .Group(group => { group.Resources("Rooms"); group.Date(true); })
          .Resources(resource =>
          {
              resource.Add(m => m.RoomId).Title("Room").Name("Rooms").DataTextField("Text").DataValueField("Value").DataColorField("Color").BindTo(new[] {
                  new { Text = "Meeting Room 101", Value = 1, Color = "#6eb3fa" },
                  new { Text = "Meeting Room 201", Value = 2, Color = "#f58a8a" }
              });
              resource.Add(m => m.Attendees)
                  .Title("Attendees")

Hi,

I have tested the scenario that you described on our online demos and locally but could not replicate a similar behavior. Would you please elaborate a little bit how is your scenario different than it so we could be more helpful? Sending a sample isolated project may be helpful too.
