I have done some code but it has bug when i select first time it works but if i go to change again on clicking select it sort item with the previous value and after when dropdown open then i select then it sort with current value.

Here is my code

var options = {
  valueNames: [ 'hotelName', 'price', 'star' ]
};

var hotelList = new List('hotels', options);

$('.sort').change(function(){
  var selection = $(this).val();
  console.log(selection);
  $(this).attr('data-sort', selection);
});

You should use the hotelList.sort function for that:

var options = {
  valueNames: [ 'hotelName', 'price', 'star' ]
};

var hotelList = new List('hotels', options);

$('select.sort').change(function(){
  var selection = $(this).val();
  hotelList.sort(selection);
});

$('button.sort').click(function() {
  hotelList.sort($(this).data('sort'));  
});

    <option value="hotelName">Hotel Name</option>
    <option value="price">Price</option>
    <option value="star">Star</option>
  </select>
