I am working on a project and there I am getting a value from input tag and then insert input value in a div and appending on screen with children element.
And What I want that when user click on children element then parent div would be removed and for this I'm using a function. That is working when I am using by default a section but when I append a section and then click on that's children where a function call like when user click on it's children parent section would be removed but my functionality not working.
$('#btn').click(function() {
  var menuFieldName = $('#text').val();
  $('.div').append('<div class="a">' + menuFieldName + '<span>X</span></div>');
  $('#text').val('');
});
$('.div .a span').on('click', function() {
  $(this).parent().remove();
});.a {
  display: inline-block;
  padding: 5px 35px 5px 10px;
  position: relative;
  background: #eee;
  border-radius: 20px;
  margin: 10px;
}
.a span {
  position: absolute;
  top: 0;
  right: 0;
  background: #333;
  color: #fff;
  height: 28px;
  width: 28px;
  text-align: center;
  line-height: 28px;
  border-radius: 30px;
