Reactjs Firebase redux数据映射状态到道具？

当状态发生变化时，如何从firebase获取数据？My mapStateToProps接收货物数据，但firebaseConnect仅发射一次？如何使用状态刷新数据

 mapStateToProps = (state, ownProps) => {
  const questions = state.firebase.ordered.questions;
  const page = state.homeReducer.page

 //  console.log(state)
   return {questions,page}
 }  

export default compose(

  firebaseConnect((props, store) => {

  const page = store.getState().homeReducer.page;
  console.log('fire')
    return [
      { type: 'once', path: '/questions' ,queryParams: [ 'limitToFirst='+page ]  }
    ]
  }),

  connect(mapStateToProps),
