How to fire dynamic link buttons in modalpopupextender

Hi guys I have the following on my aspx page:

<asp:UpdatePanel ID="updPnlWorkOrder" runat="server"><ContentTemplate><asp:HiddenField ID="HiddenField6" runat="server" /><cc1:ModalPopupExtender ID="modalPopupExtender6" runat="server" BackgroundCssClass="modalBackground"
                                DynamicServicePath="" Enabled="True" PopupControlID="pnlConfirmation6" TargetControlID="HiddenField6"
                                DropShadow="True"></cc1:ModalPopupExtender><asp:Panel ID="pnlConfirmation6" runat="server" Style="display: none; color: Black;
                                background-color: White; border-width: 2px; border-color: Black; border-style: solid;
                                padding: 20px; width: 650px;"><span style="position: relative; float: right; bottom: 28px; left: 30px;"><asp:ImageButton ID="ImageButton4" runat="server" CausesValidation="false" ImageUrl="../../Images/Close_Box_Red.png"
                                        OnClick="ImageButton1_OnClick" /></span><table><tr><td id = "tdListProjs" runat = "server" colspan="2" style=" padding:50px 0px 50px 0px">"The following Work Orders exist already: "</td></tr><tr><td></td></tr><tr><td><asp:Button ID="btnCancelWorkOrder" CssClass="button" runat="server" Text="Cancel"
                                                OnClick="btnCancelWorkOrder_Click" /></td><td><asp:Button ID="btnCreateWorkOrder" CssClass="button" runat="server" Text="Create"
                                                OnClick="btnCreateWorkOrder_Click" /></td></tr><tr><td>&nbsp;</td></tr></table></asp:Panel></ContentTemplate></asp:UpdatePanel>

Behind I create links automatically based on certain conditions:

protected void CreateProjectLinks(DataSet ds)
    {   
        List<LinkButton> projLinks = new List<LinkButton>();

        int rowCount = ds.Tables[0].Rows.Count;
        if (ds.Tables[0].Rows.Count > 0)
        {
            for (int i = 0; i<=rowCount - 1; i++)
            {
                var itemKey = ds.Tables[0].Rows[i]["projectNumber"].ToString();
                var itemValue = ds.Tables[0].Rows[i]["projectName"].ToString();
                LinkButton lnk = new LinkButton();
                lnk.Text = itemValue + "(# " + itemKey + ")";
                lnk.Click += new System.EventHandler(lnk_Click);
                lnk.CommandArgument = itemKey;
                projLinks.Add(lnk);
            }
        }


        foreach (LinkButton lnkButton in projLinks)
        {
            tdListProjs.Controls.Add(lnkButton);
            Label lblColon = new Label();
            lblColon.Text = "; ";
            tdListProjs.Controls.Add(lblColon);
        }
    }

    protected void lnk_Click(object sender, EventArgs e)
    {  
        LinkButton lnk = (LinkButton)(sender);
        DBProject proj = new DBProject(Convert.ToInt32(lnk.CommandArgument));
        Session["SelectedProject"] = proj;
        Response.Redirect("ViewProject.aspx", true);
    }

The modal pop up shows fine, but if I click any of the dynamic links, they will not redirect, instead the modal popup just closes.  Any ideas on how to get the redirect to fire? Thanks.
