The idea is that all of these routes will pass the user through to the same view/vm, but the parameter will determine content that is displayed after an ajax call). The routing itself works well, but the title is always passed through from the first route in the list. activate: function () { router.makeRelative({moduleId: 'viewmodels'}).map([ { route: 'grid
