    Try to use this:

    <html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <script runat="server">
        protected void Page_Load(object sender, EventArgs e) {
            if (!X.IsAjaxRequest) {
                this.Store1.DataSource = this.Data;
                this.Store1.DataBind();
            }
        }

        private object[] Data {
            get {
                return new object[]
            {
                new { header = "3m Co" },
                new { header = "Coca Cola" },
                new { header = "Pepsi Co" },
            };
            }
        }

        protected void ShowHello(object sender, DirectEventArgs e)
        {
            X.Msg.Alert("Hello", "Hello " + e.ExtraParams["SayHelloTo"]).Show();
        }

    </script>
