title: blur event not firing on iOS Mobile Safari in Sencha Touch
body: <p>I'm using iOS 5.0.1, and Sencha Touch 2-rc1. I have a search input field where the focus event is getting triggered, as well as the submit event when I press 'Search' on the on-screen keyboard. The blur event doesn't get triggered when I expect it to, which would be when the 'Done' key is pressed, or the viewable area is tapped.</p>
  
  <p>Note that the blur event IS getting triggered on my laptop in Chrome.</p>
