title: KendoUI DatePicker validation when multiple date fields are on a page
body: <p>I'm looking to validate date fields on a page, which is simple (see <a href="http://jsbin.com/ufimom/4/edit" rel="nofollow">this JSBin</a>). BUT, when a page has multiple date fields on a page things start to get wacky...</p>
  
  <p>See <a href="http://jsbin.com/ufimom/279/edit" rel="nofollow">this JSBin</a> and play around with invalid dates.</p>
  
  <p>The invalid message doesn't know which input to bind to, causing error messages on the wrong inputs. Is there a way to trigger the correct input field?</p>
