RadGrid Delete Button Not Opening RadWindow

[PPI Itdept]

I'm currently changing my code from Q3 2007 to Q1 2008 with RadGrid and have a problem. I created a Delete Column inside the grid and when the user clicks on it is supposed to open the RadWindow but it doesn't. It worked in Q3 2007 but not here. Is there something I'm missing ?

Thanks

Here is the code behind

protected void rgCategory_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                HyperLink deleteLink = e.Item.FindControl("DeleteLink") as HyperLink;
                deleteLink.Attributes["href"] = "#";
                deleteLink.Attributes["onclick"] = string.Format("return ShowDeleteCategoryForm('{0}','{1}','{2}');", e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["CategoryID"], e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ProductID"], e.Item.ItemIndex);
            }

            if (e.Item is GridCommandItem)
            {

                HyperLink addLink = e.Item.FindControl("AddLink") as HyperLink;
                addLink.Visible = true;
                addLink.Attributes["href"] = "#";
                addLink.Attributes["onclick"] = string.Format("return ShowInsertCategoryForm('{0}','{1}');", productID, systemID);

            }

        }

    protected override void RaisePostBackEvent(IPostBackEventHandler sourceControl, string eventArgument)
        {
            base.RaisePostBackEvent(sourceControl, eventArgument);

            if (sourceControl is RadGrid)
            {
                switch (eventArgument)
                {
                    case "RebindAndNavigateCategory":
                        rgCategory.MasterTableView.SortExpressions.Clear();
                        rgCategory.MasterTableView.GroupByExpressions.Clear();
                        rgCategoryrgCategory.MasterTableView.CurrentPageIndex = rgCategory.MasterTableView.PageCount - 1;
