How to avoid input value copying on click of button

Everything works fine but it also copies the value inside input button e.g if i write 1st in the input, 1st will also be copied on click of the button, does anyone has any resolution ?

$(function(){
  $(".btn-copy").on('click', function(){
    var ele = $(this).closest('.example-2').clone(true);
    $(this).closest('.example-2').after(ele);
  })
})
