title: When using onChange with React, spaces are not registered
body: <p>I am trying to save a user's input by using the onChange method described here: <a href="https://facebook.github.io/react/docs/forms.html" rel="noreferrer">https://facebook.github.io/react/docs/forms.html</a>.</p>
  
  <p>I have this line of code for my input:</p>
  
  <pre><code>      &lt;input type="text" onChange={this.changeTitle} ref="title" value={this.props.quiz ? this.getTitle() : ''}&gt;&lt;/input&gt;
  </code></pre>
  
  <p>However, when I call <code>this.refs.title.value</code> after pressing the spacebar, the space is not registered.  Is there anyway I can register this space? </p>
