Okey, I changed this. Now it empties the list and adds all archived stories each time you check the checkbox. Would be nicer to only generate it once the first time the checkbox i checked but I don't think this is a big problem, since the client already got all stories loaded. What we could do in a future change is to make an ajax call the first time the checkbox is checked and load the archived stories from the server instead of loading everything on page load.
