Как позвонить в крест домена службы WCF из jQuery и AJAX с параметрами

I have one Cross Domain WCF. I have already implemented the CORS on the service.

If the method don't have any parameter, then I can call it using JQuery Ajax.

But the problem is, when the method is having any parameter then some error is occurred after the JQuery Ajax call.

$.support.cors = true;
 $.ajax({
   url: servicePath,
   crossDomain: true,
   type: 'POST',
   async: false,
   cache: false,
   data: '{"name": "xyz"}',
   contentType: "application/json; charset=utf-8",
   dataType: 'json',
   processData: true,
   success: function (response) {
     alert('s');
   },
   error: function (error) {
     alert(error.status + ' : ' + error.statusText);
   }
 })

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{
  [OperationContract]
  [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped,
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json)]
  public string GetName(string name)
  {
    return "Result !";
  }
}
