title: How to make e.target.value in React-native?
body: <p>I am transferring React to React Native.<br>
  But I am sticked to the problem using e.target.value.<br>
  This is a code of React that works well.</p>
  <pre><code>  _searchContact = (e) =&gt; { this.state.keyword 
      this.setState({
        keyword : e.target.value
      });
    }
  
  ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ
  
      &lt;input
        name=&quot;keyword&quot;
        placeholder=&quot;Search&quot;
        value={this.state.keyword} 
        onChange={this._searchContact} 
      /&gt;
  </code></pre>
  <p>And I tried to write again with the way of React-native<br>
  But it doesn't work.</p>
  <pre><code>  _searchContact = (e) =&gt; { 
      this.setState({
        keyword : e.nativeTarget.value
      });
    }
  
        
  
       &lt;TextInput
          style={{height: 40, borderColor: 'gray', borderWidth: 1}}
          name=&quot;keyword&quot;
          placeholder=&quot;Search&quot;          
          onChangeText={this._searchContact}        
          value={this.state.keyword} 
      /&gt;
  </code></pre>
