Send Android class to WCF webservice

I am trying to use REST, to send to an exposed webservice. But what I get is 400 (Bad Request.)

How do you property send a model across from REST, that will correctly map up to the model on the other side. What I don't want to do, is have all 100 parameters exposed individually in the connection point.

    [OperationContract]
    [WebInvoke(
        Method = "POST",
        UriTemplate = "SaveData",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        RequestFormat = WebMessageFormat.Json)]
    void SaveData(datum data);

But what I am unable to do is pass a valid datum object.

     // Build JSON string
     JSONStringer vehicle;
    try {
        vehicle = new JSONStringer()
             .object()
                 .key("datum")
                     .object()
                         .key("ID").value(5)
                         .key("Name").value("test")
                         .key("No").value(54)
                         .key("Description").value("Test")
                     .endObject()
                 .endObject(); 

      HttpPost request = new HttpPost(address + "/SaveData");
     Log.d("WebInvoke", "Connection : " + address + "/SaveData");
     request.setHeader("Accept", "application/json");
     request.setHeader("Content-type", "application/json");
         StringEntity entity = new StringEntity(vehicle.toString());
         Log.d("StringEntity", vehicle.toString());
         request.setEntity(entity);

         // Send request to WCF service
         DefaultHttpClient httpClient = new DefaultHttpClient();
         HttpResponse response = httpClient.execute(request);

         Log.d("WebInvoke", "Saving : " +    response.getStatusLine().getStatusCode());
             // Saving : 400

Datum Class:

[DataContract]
public partial class datum
{
    [DataMember(Name = "ID")]
    public int ID { get; set; }
       [DataMember(Name = "Name")]
    public string Name { get; set; }
     [DataMember(Name = "No")]
    public Nullable<int> No { get; set; }

        [DataMember(Name = "Description")]
    public string Description { get; set; }
}

It should be:

vehicle = new JSONStringer()
             .object()
                 .key("data")
                     .object()
                         .key("ID").value(5)
                         .key("Name").value("test")
                         .key("No").value(54)
                         .key("Description").value("Test")
                     .endObject()
                 .endObject();
