Web API Post

This is the display side

function Load () {
$.ajax ({
Type: "Post",
URL: "Http://localhost:63211/api/MeetingRoomService/AddMeetiongType",
DataType: "JSON",
Data: {"Typename": "123"},
Success:function (data) {
Rendercontactlist (data);
alert (data.data);
},error:function (XMLHttpRequest, Textstatus, Errorthrown) {

alert (data.data);
}
});
}

This is the service side

[HttpPost]
Public resultentity<bool> addmeetiongtype ([Frombody]meetingtype MT)
{

resultentity<bool> result = new resultentity<bool> ();
Result.errors = new list<errorentity> ();
Errorentity error = new errorentity ();
Result.action_code = ActionCode.SUCCESS.ToString ();
Try
{
