title: Redux Selector not triggering when I'm calling it from mapstatetoprops
body: <p>Now I'm working in react-redux. I'm trying to get questions from state one-by-one. Generated unique ID to store the questions in the state, after user submits,answer also store with the question.</p>
  
  <p>Uniqueid: { 
       Question: question goes here,
       Answer: ''
  }</p>
  
  <p>React component to render the question. I used selector in the mapstatetoprops to select question from state.</p>
  
  <p>Now is my question:
    Selector triggers first time perfectly. After user submits the question answer also updated. After that, selector not triggering, I can't find why?</p>
