    can not get DataSourceProxy to work

    I am trying to make nearly the exact implementation of the sample "Paging And Sorting" on the examples page.
    but, when i put the DataSourceProxy item in ext:Store, i get an empty result set.

    If i remove it, i get only the 10 records (which is the limit in my case).
    You can see the following code for the sample, but its not much different than the sample.
    Any suggestions for that behaviour ?

        <asp:ObjectDataSource ID="ObjectDataSource1" SelectMethod="GetMyList"
            OnSelected="ObjectDataSource1_Selected" TypeName="oo.ObjectData" runat="server">
                <asp:Parameter Name="start" DefaultValue="1" Type="Int32" />
                <asp:Parameter Name="limit" DefaultValue="10" Type="Int32" />
                <asp:Parameter Name="sort" DefaultValue="" />
                <asp:Parameter Name="dir" DefaultValue="" />
                <asp:Parameter Name="count" Direction="Output" Type="Int32" />
        <ext:Store ID="Store1" runat="server" AutoLoad="true" RemoteSort="true" DataSourceID="ObjectDataSource1">
                <ext:DataSourceProxy />
                <ext:JsonReader ReaderID="id">
                        <ext:RecordField Name="FirstName" />
    namespace oo
        using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
        using System.Data;
        using Microsoft.Practices.EnterpriseLibrary.Data;

        public class ObjectData
            public static DataTable GetMyList(
                int start, 
                int limit, 
                string sort, 
                string dir,
                out int count
                    Database db = DatabaseFactory.CreateDatabase();
                    string sqlCommand = "SP_GetMyList";
                    DbCommand dbCommand = db.GetStoredProcCommand(sqlCommand);
                    db.AddInParameter(dbCommand, "start", DbType.Int32, start);
                    db.AddInParameter(dbCommand, "limit", DbType.Int32, limit);
                    db.AddInParameter(dbCommand, "sort", DbType.String, sort);
                    db.AddInParameter(dbCommand, "dir", DbType.String, dir);
                    db.AddOutParameter(dbCommand, "TotalCount", DbType.Int32, count);
                    ds = db.ExecuteDataSet(dbCommand);
                    count = Convert.ToInt32(db.GetParameterValue(dbCommand, "TotalCount"));
                catch (Exception ex)
                return ds.Tables[0];

    You must define OnRefreshData handler and rebind data in this handler. In example it is shown.
