title: react native TextInput onBlur get unedfined at android
body: <p>My react-native version is 0.38.0</p>
  
  <pre><code>&lt;TextInput onBlur={ (event) =&gt;
     this.handleBlurCheck(event.nativeEvent.text,params) } /&gt;
  </code></pre>
  
  <p>In function <code>handleBlurCheck</code>, I get the value at iOS, but I get <code>undefined</code> at Android.</p>
  
  <p>How to get value when <code>TextInput</code> is blurred on android platform?</p>
  
  <p>The <code>nativeEvent</code> object on iOS:</p>
  
  <pre><code>nativeEvent:{
      eventCount: 5,
      target: 1046,
      text: '56'
  }
  </code></pre>
  
  <p>The <code>nativeEvent</code> on Android:</p>
  
  <pre><code>nativeEvent:{
      target: 1046,
  }
  </code></pre>
