AlertTemplate is not set on List

Question

I using following code to change AlertTemplate for a list. But it dosen't work. When I look at the XML for the template variable it's the correct XML. But when I look att list.AlertTemplate after that I have set the template object to it, it's XML is still unchanged. What should I do for to solve it?

                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(SPUtility.GetGenericSetupPath(@"TEMPLATE\XML") + "\\SubscribeOrdersAlert.xml");
                try
                {
                    SPList list = site.RootWeb.GetList("/Lists/Tillggsbestllningar");
                    SPAlertTemplate template = new SPAlertTemplate();
                    template.Xml = xmlDoc.InnerXml;
                    template.Name = "Tilläggsbeställningar";
                    list.AlertTemplate = template;
                    list.ParentWeb.AllowUnsafeUpdates = true;
                    list.Update();
                }

I deployed the xml with a stsadm-command and then it worked.

stsadm -o updatealerttemplates- url http://mysite.com -filename c:\SubscribeOrdersAlert.xml
