in react-router, it changes url but doesn't navigate?

Question

I have a button, in the onclick I do transitionTo, the url updates properly but it stays on the same page. I stepped thru transitionTo, it finds the route, does location.push, just never navigates anywhere?

var routes = (
    <Route handler={App} path="/">
        <DefaultRoute handler={LandingPage}/>
        <Route name="createEvent" path="createEvent" handler={CreateEvent}/>
        <NotFoundRoute handler={NotFound}/>
    </Route>
);

React 13.3, React-Router 13.3
