jQuery Autocomplete works on localhost but not working on remote server in asp.net

Question

I have a pharmacy web application, written in vb.net, where a user searches for a medicine by name using the auto-complete function, which pulls data from the database table. This works perfectly on local host when debugging in Visual Studio, but does not work on a remote server host. Can someone please check my code and correct it?

Here is the .aspx code

    <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.0.min.js" type="text/javascript"></script>
    <script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/jquery-ui.min.js" type="text/javascript"></script>
    <link href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/themes/blitzer/jquery-ui.css" rel="Stylesheet" type="text/css" />
    <script type="text/javascript">
        $(function () {
            $("[id$=txtSearch]").autocomplete({
                source: function (request, response) {
                    $.ajax({
                        url: '<%=ResolveUrl("~/AddMeds.aspx/GetNames/") %>',
                       data: "{ 'prefix': '" + request.term + "'}",
                       dataType: "json",
                       type: "POST",
                       contentType: "application/json; charset=utf-8",
                       success: function (data) {
                           response($.map(data.d, function (item) {
                               return {
                                   label: item.split('-')[0],
                                   val: item.split('-')[1]
                               }
                           }))
                       },
                       error: function (response) {
                           alert(response.responseText);
                       },
                       failure: function (response) {
                           alert(response.responseText);
                       }
                   });
               },
               select: function (e, i) {
                   $("[id$=hfNameId]").val(i.item.val);
               },
               minLength: 1
           });
       });
    </script>

Here is the .vb code

<WebMethod()>
Public Shared Function GetNames(prefix As String) As String()
    Dim customers As New List(Of String)()
    Using conn As New SqlConnection()
        conn.ConnectionString = ConnectionStrings("conString").ConnectionString
        Using cmd As New SqlCommand()
            cmd.CommandText = "SELECT top(10) [MedicineName], [IdNo] FROM [MedsName] where [MedicineName] like @SearchBar + '%'"
            cmd.Parameters.AddWithValue("@SearchBar", prefix)
            cmd.Connection = conn
            conn.Open()
            Using sdr As SqlDataReader = cmd.ExecuteReader()
                While sdr.Read()
                    customers.Add(String.Format("{0}-{1}", sdr("MedicineName"), sdr("IdNo")))
                End While
            End Using
            conn.Close()
        End Using
    End Using
    Return customers.ToArray()
End Function
