title: Typeahead blur event not fired on iPhone
body: <p>I have a simple bootstrap <a href="https://angular-ui.github.io/bootstrap/#!#typeahead" rel="nofollow noreferrer">typeahed</a> directives which works fine. 
  But on an iPhone the drop down menu doesn't closed on blur (when I touch else where on my page). </p>
  
  <p>It does works when I try on the typeahaed demo page on an iPhone.</p>
  
  <p>Do I need to do anything special for the blur events to get fired when clicking on my body?</p>
