title: The field 'Date' must be a date MVC 4
body: <p>Im facing this error when im using my jQuery datepicker.</p>
  
  <p>jQuery:</p>
  
  <pre><code>$( ".datepicker" ).datepicker({ 
      defaultDate: +7,
      autoSize: true,
      dateFormat: 'dd.mm.yy',
  }); 
  </code></pre>
  
  <p>Model:</p>
  
  <pre><code>[DisplayName("Date")]
  [DisplayFormat(DataFormatString = "{0:dd.MM.yyyy}", ApplyFormatInEditMode = true)]
  [Required(ErrorMessage = "Date is required")]
  public DateTime Date { get; set; }
  </code></pre>
  
  <p>So I want the date format to be like <code>dd.MM.yyyy</code>, and when I select the date using the datepicker it is correctly added to the field. But also in the same second, an validation error appears saying <code>The field 'Date' must be a date</code>.</p>
  
  <p>I did test with writing manually the date in the format <code>dd/MM/yy</code> and then it looks like it is working. So somewhere the validator looks for that format, but I cant find out where to modify it.</p>
