React 0.14.8 doesn't trigger Router's createElement

Question

I'm trying to bump React from 0.13.3 to 0.14.8, but my old setup doesn't work anymore. I've solved all issues very easily, but now I'm stuck and I can't find any hint in the upgrad guide(s).

Here is my setup:

const createElement = (Component, props) => <Component {...props} {...store.getState()}/>
const routes = <Router createElement{createElement} history={browserHistory}><Route>...</Route></Router>;
store.subscribe(() => ReactDOM.render(routes, containerElement));

So basically, everytime the store changes, ReactDOM.render is called and routes is rendered. routes should call createElement on render and did just that in 0.13, but not anymore in 0.14. Only when the route/url changes, the UI is updated with the latest data.

Any idea where the problem is coming from (React, ReactRouter, Redux) and how to debug/fix are most welcome!
