You should use event delegation

Event delegation allows us to attach a single event listener, to a parent element, that will fire for all descendants matching a selector, whether those descendants exist now or are added in the future. Both 

on()

 and 

delegate()

functions allow us to perform event delegation.

  

added a container class

 <ul>
  <li class='list'>remove box100</li>
  <li class='list'>remove box200</li>
  </ul>
<div class="box-container">
  <div class='box' box='box1'>add box1</div>
  <div class='box' box='box2'>add box2</div>
  <div class='box' box='box3'>add box3</div>
  <div class='box' box='box4'>add box4</div>
  <div class='box' box='box5'>add box5</div>
</div>

   $('.box-container').on('click',".box", function(){
     var txt = $(this).attr('box');
    $('ul').append("<li class='list'>remove "+txt+"</li>");
    });

     $('ul').on('click','.list', function(){
     $(this).remove();
     });
