bootstrap datepicker can be less than start date

function populateEndDate() {
  var date2 = $('#dateStart').datepicker('getDate');
  date2.setDate(date2.getDate() + 1);
  $('#dateEnd').datepicker('setDate', date2);
  $("#dateEnd").datepicker("option", "minDate", date2);
}

$(document).ready(function() {

  $("#dateStart").datepicker({
    dateFormat: "dd-M-yy",
    minDate: 'dateToday',
    onSelect: function(date) {
      populateEndDate();
    }
  }).datepicker("setDate", new Date());
  $('#dateEnd').datepicker({
    dateFormat: "dd-M-yy",
    minDate: 1,
    onClose: function() {
      var dt1 = $('#dateStart').datepicker('getDate');
      var dt2 = $('#dateEnd').datepicker('getDate');
      if (dt2 <= dt1) {
        var minDate = $('#dateEnd').datepicker('option', 'minDate');
        $('#dateEnd').datepicker('setDate', minDate);
      }
    }
  }).datepicker("setDate", new Date());
});
