why closest function in jquery dont work on new table row?

i have HTML Codes which has table and row with drop down list

<tr>
      <td class="col-sm-3"> 
        <select class="form-control" name="classrooms[]">
                    <option value="" disabled>Select Room</option>
                    @foreach($rooms as $room)
                    <option value="{{$room->id}}">{{$room->description}}</option>
                    @endforeach
                        </select>
                    
             </td>
                <td class="col-sm-3"> 
        <select class="form-control" name="classroomstype[]">
                    <option value="" disabled>Select Room</option>
                    @foreach($rooms_type as $type)
                    <option value="{{$type->id}}">{{$type->description}}</option>
                    @endforeach
                        </select>
                    
             </td>
            <td class="col-sm-3">
                <input type="number"  class="form-control" name="classroomsnumber[]" />
                 @error('classroomsnumber')
                         <span class="invalid-feedback" role="alert">
                         <strong>{{ $message }}</strong>
                        </span>
                       @enderror
            </td>
              <td class="col-sm-3"> 
                <a href="javascript:void(0);" class="btn btn-primary addmore" ><i class="fa-solid fa-plus"></i></i></a>
                <a  href="javascript:void(0);" class="btn btn-danger remove" ><i class="fa-solid fa-circle-minus"></i></a>

            </td>
    </tr>

and Jquery for above HTML code to make new Row Dynamically

<script>
    $(document).ready(function() {
  $(".addmore").on('click',function(){

        data ='<tr>'+ $(this).closest('tr').html() +"</tr>";
        $('#myTable').find('tbody:last').append(data);
});
 
    $(".remove").on('click',function(){
        $(this).closest('tr').remove();
});
});
</script>

it work what i want , but only the first button work to make new rows not every row button work and also remove work only “One Time”.
