  <p>Both of these inputs are only updated if they are blurred. Hitting escape should
  empty them. Follow these steps and observe the difference:</p>
  <ol>
    <li>Type something in the input. You will see that the model is not yet updated</li>
    <li>Press the Escape key.
      <ol>
        <li> In the first example, nothing happens, because the model is already '', and no
        update is detected. If you blur the input, the model will be set to the current view.
        </li>
        <li> In the second example, the pending update is cancelled, and the input is set back
        to the last committed view value (''). Blurring the input does nothing.
        </li>
      </ol>
    </li>
