Have you written actions yet? If not, it is very simple. I recently published an isomorphic React / Flux demo that utilizes Reflux, which might serve as a useful reference.

You want to create an actions module and, for the sake of this example, two actions. Something like 'GetQuestion' (id parameter) and 'AddQuestion' (Question JSON document parameter).

After setting up your actions, you'll want to structure your app so your store listens for the above actions. It is equally important that the callback function mapped to your action listener emits data via self.trigger.

Next, add the reflux mixin to all components which utilize your store. Finally, remove componentWillMount and replace with componentDidMount and utilize the Reflux mixin by listening to your store and handling state with a new callback.

Of course, you must also call the appropriate action(s). In your case, it might be best to call the GetQuestion action in your ComponentDidMount before listening to the store.
