title: TextInput with value doesn't change value
body: <p>In my react-native app i have an API that I'm retrieving data from, and I'm setting the data inside my input values, user should be able to edit those inputs and update, but when i try to type in the input it won't type anything and the value stays as it is, here is the TextInput code:</p>
  
  <pre><code>&lt;TextInput
     placeholder= Email
     value={this.state.info.email}
     onChangeText={email =&gt; this.setState({ email })}/&gt;
  </code></pre>
