Update DataGrid inside AJAX accordion

Question

I have an AJAX accordion from the ajax control toolkit on a page with a datagrid inside on of the panels. I have a custom itemtemplate for the one column to create a multiline textbox when I click edit on the row. When I click update on the row, the original content of the textbox gets rendered into the textbox. It is supposed to update and go back to the literal not the textbox. When I put the DataBind() into a !IsPostBack, it doesnt get rendered when I click on the accordion pane. Any ideas?

Code:

    protected void Page_Load(object sender, EventArgs e)
        {
            announ.HeaderStyle.CssClass = "header";
                        announ.Width = Unit.Percentage(100);
                        announ.GridLines = GridLines.None;
                        announ.AutoGenerateColumns = false;
                        announ.CellPadding = 10;
                        announ.CellSpacing = 0;
                        announ.HorizontalAlign = HorizontalAlign.Center;
                        announ.HeaderStyle.Font.Bold = true;
                        announ.EnableViewState = false;
                        announ.AlternatingItemStyle.BackColor = System.Drawing.Color.GhostWhite;
                        //announ.DeleteCommand += AnnounDeleteCommand;
                        announ.EditCommand += announ_EditCommand;
                        announ.UpdateCommand += announ_UpdateCommand;
                        announ.CancelCommand += announ_CancelCommand;
                        announ.DataKeyField = "id";
                        var tc1 = new TemplateColumn
                                      {
                                          HeaderTemplate = new
                                              DataGridTemplate(ListItemType.Header, "Announcement"),
                                          ItemTemplate = new DataGridTemplate(ListItemType.Item, "announcement_text"),
                                          EditItemTemplate = new
                                              DataGridTemplate(ListItemType.EditItem, "announcement_text")
