Jquery UI Widget create and destroy
<p>In "learning Jquery Third Edition" I found these lines:</p>

<blockquote>
  <p>Destroying widgets.... Calling .myWidget('destroy') will remove the
  myWidget widget from the page. The widget factory does most of the
  work, but if we have modified parts of the document inside _create (as
  we did here);so we need to clean up after ourselves.</p>
</blockquote>

<p>However, when creating a new widget and I can't imagine a situation in which we don't modify _create function. Could you give me an example of doing so.</p>
