KendoDropDownList WebService JSON serilaized list datasource

Hello,
I'm trying to bind a kendodropdownlist data source to an asp.net c# webservice

 <p>
                   <label for="dates">Date:</label><input id="dates" style="width: 270px" />
                </p>
 
 
$("#dates").kendoDropDownList({
            optionLabel: "Select date...",
            dataTextField: "datestamp",
            dataValueField: "datestamp",
            autoBind: false,
            dataSource: {
                transport: {
                    read: {
                        type: "POST",
                        url: "CGCSService.asmx/DropDownListDates",
                        //contentType: "application/json; charset=utf-8",
                        dataType: "json"
                    },
                    success: function (msg) {
                        alert(msg.d)
                        options.success($.parseJSON(msg.d))
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                        //alert(textStatus);
                    }
                },
                schema: {
                    data: "datestamp"
                }
            }
        });
 
 
 
 
[WebMethod]
    public String DropDownListDates()
    {
        try
        {
            var connectString = WebConfigurationManager.ConnectionStrings["CGCS"].ConnectionString;
            using (SqlConnection sqlconn = new SqlConnection(connectString))
            {
                using (System.Data.SqlClient.SqlCommand sqlCmd = sqlconn.CreateCommand())
                {
                    sqlCmd.CommandText = "select distinct CONVERT(DATE,datestamp,101) as datestamp from serverdataHistory order by datestamp desc";
                    sqlCmd.CommandTimeout = 0;
                    sqlconn.Open();
 
                    DataSet ds = new DataSet();
                    SqlDataAdapter da = new SqlDataAdapter(sqlCmd);
                    da.Fill(ds);
 
                    return JsonConvert.SerializeObject(ds);
 
                   
                   
                }
            }
        }
        catch (Exception)
        {
            return null;
        }
    }
