title: Data annotations do not work with jQuery unobtrusive validation
body: <p>Live example: <a href="http://mvc.renethomassen.dk/" rel="nofollow noreferrer">http://mvc.renethomassen.dk/</a></p>
  
  <p>I have used jQuery unobtrusive validation with data annotations (MVC 4), when I publish my website, properties with multiple annotations do not work, validate.</p>
  
  <p>This works:</p>
  
  <pre><code>[Required(ErrorMessage = "Skriv venligst dit navn")]
  public string Navn { get; set; }
  </code></pre>
  
  <p>The following does not work (it works on localhost). Why?</p>
  
  <pre><code>[Required(ErrorMessage = "Skriv venligst din emailadresse")]
  [EmailAddress(ErrorMessage="Angiv en gyldig emailadresse")]
  public string EmailAdresse { get; set; }
  </code></pre>
