Clojurians Log v2

I'm wondering if anyone can point out what I'm doing wrong. According to the docs for the mutate function (https://github.com/omcljs/om/wiki/Documentation-(om.next)#parser) in the parser, if the return map from my mutate function includes a :value {:keys [:todos/list]} then any components with :todos/list in their IQuery should be re-rendered. I cannot get it to work though. As soon as I add :todos/list to the end of my transact! transaction though, everything works. Am I misunderstanding what adding :value {:keys [:todo/list]} to my mutate function is meant to do?
