title: jquery datepicker - dynamic altfield issue
body: <p>I have multiple datepickers on a page... all seems to be working fine except I the altfield part...</p>
  
  <p>Is something like this possible??</p>
  
  <pre><code>$(document).ready(function(){
  
      $( ".datepicker" ).datepicker({
          beforeShowDay: function(date){ return [(date.getDay() == 1 || date.getDay() == 4), ""] },
          showOn: "button",
          buttonText: "Book now...",
          showWeek: true,
          firstDay: 1,
          onSelect: function(date) { 
              $(this).parent().find('.selecteddate').prepend("Date: " + $(this).parent().find('.datepicker').val() + " - &lt;a href='javascript:;' class='cleardate'&gt;clear date&lt;/a&gt;"); 
              $(this).parent().find('button').hide();
          },
          dateFormat: "DD, d MM, yy",
  
          altField: $(this).closest('div').find('.datepickeralt'),
  
          altFormat: "dd/mm/yy",
          navigationAsDateFormat: true,
          minDate: 0,
      });
  
      $(".cleardate").live('click',function(){
          $(this).closest('div').find('.datepicker').datepicker("setDate", null);
          $(this).closest('div').find('.datepickeralt').val("");
          $(this).closest('div').find('button').show();
          $(this).parent().html("");
      });
  
  });
