title: jquery mobile error - cannot call methods on button prior to initialization; attempted to call method 'disabled'
body: <p>According to the documentation (<a href="http://jquerymobile.com/demos/1.2.0/docs/api/events.html">http://jquerymobile.com/demos/1.2.0/docs/api/events.html</a>), the pageinit event should be called after all the widgets and plugins for a jQuery mobile page have been executed. So, I believe I should be able to interact with elements on that page with impunity in the event callback. However, I listen for the page to initialize and then try to interact with a button on the page, and I get the following error:</p>
  
  <blockquote>
    <p>cannot call methods on button prior to initialization; attempted to
    call method 'disabled'</p>
  </blockquote>
  
  <p>I've put together a codepen, to show you:</p>

  <p>What gives? Does the pageinit not work as documented or is this a bug?</p>
