title: Cannot type anything in react native TextInput component
body: <p>I am new to react-native. I am doing a simple salary calculator component for practice. I have two TextInput components, but I can't seem to type anything in them. Here is the code for my component:</p>
  
  <pre><code>class SueldoCalc extends Component {
    constructor(props)
    {
       super(props);
    }
  
   calcSalario()
   {
     console.log("Calculating");
   }
  
  render() 
  {
  return (
    &lt;View&gt;
        &lt;Text&gt;Entre las horas trabajadas:&lt;/Text&gt;
        &lt;TextInput /&gt;
        &lt;Text&gt;Entre el rate por hora:&lt;/Text&gt;
        &lt;TextInput /&gt;
        &lt;TouchableHighlight onPress={this.calcSalario}&gt;
          &lt;Text&gt;Calcular salario...&lt;/Text&gt;
        &lt;/TouchableHighlight&gt;
    &lt;/View&gt;
  );
  
  }
  
  }
  </code></pre>
  
  <p>I tried subscribing to onTextChange events, but nothing. This is so basic, I can't find anything out there. Please help! I am running the app on Android Simulator for Visual Studio.</p>
