title: React-Native: 'onBlur' is not getting fired when touched out side of the TextInput
body: <pre><code>   &lt;TextInput
          ref={ ref =&gt; this.mobileNumberRef = ref}
          keyboardType='phone-pad'
          returnKeyType='done'
          onBlur={() =&gt; Keyboard.dismiss()}
     /&gt;
  </code></pre>
  
  <p>I would like to dismiss the keyboard when touched outside of the <code>TextInput</code> area. But <code>onBlur()</code> is not getting fired.</p>
  
  <p>Can anybody let me know how to achieve this? Thank You! </p>
