title: Kendo grid with date column not sorting correctly
body: <p>I have a kendo grid with a column that is a DateTime? type.  When sorting on this column the dates are not sorting correctly.  It appears to be sorting with respect to month not with respect to the whole date.  Is there some sort of magic that needs to be done in order for it to sort on the whole date and not just the month and day?  Below is the table.  The Paymentdate column is the DateTime? field that I'm trying to sort on.  Any help would be greatly appreciated.</p>
  
  <pre><code>@(Html.Kendo().Grid&lt;PaymentTransactionViewModel&gt;()
              .Name("payment-history-list")
              .TableHtmlAttributes(new { @class = "js-table-accordion accordion-table detail-table" })
              .Columns(c =&gt;
              {
                  c.Bound(p =&gt; p.PaymentDate).Title("Payment Date").Format("{0:d").Sortable(true);
                  c.Bound(p =&gt; p.Amount).Format("{0:c}").Title("Amount").Sortable(false);
                  c.Bound(p =&gt; p.BankAccountNickName).Title("Bank Account").Sortable(false);
                  c.Bound(p =&gt; p.ConfirmationId).Title("Confirmation ID").Sortable(false);
              })
              .Pageable()
              .Sortable()
          )
  </code></pre>
