Question solved,

I have added this script

<script>
// Add the following code if you want the name of the file appear on select
$(".custom-file-input").on("change", function() {
  var fileName = $(this).val().split("\\").pop();
  $(this).siblings(".custom-file-label").addClass("selected").html(fileName);
});
</script>
