title: React native function not getting called
body: <p>Hi I have an a button which should call a function, but when I click on the button nothing seems to happens. I have tried creating 2 desperate buttons to see if functions work individually, which they do. Although do not understand why nothing is happening with the code below</p>
  
  <pre><code>          handlePlayAgainClick () {
              dispatch(playAgain())
              goBack('BScreen')
            }
            render() {..
          const { goBack } = this.props.navigation;
        &lt;PlayAgainButtons onPress={ () =&gt; this.handlePlayAgainClick}&gt;
  </code></pre>
