когда я использовал несколько загрузок файлов, поля это не работает

Когда я использовал загрузку одного файла на странице, он работает нормально, но когда я использую несколько полей на странице, он не работает.Я хочу, чтобы решение по классам и динамическим id, и я не хочу использовать много времени на странице, если кто-нибудь знает, пожалуйста, сообщите мне.

Код URL: https://codepen.io/tushar-kumawat/pen/WYyKYG

Вот код JavaScript: 

$('#chooseFile').bind('change', function () {
    var filename = $("#chooseFile").val();
    if (/^\s*$/.test(filename)) {
        $(".file-upload").removeClass('active');
        $("#noFile").text("No file chosen..."); 
    } else {
        $(".file-upload").addClass('active');
        $("#noFile").text(filename.replace("C:\\fakepath\\", "")); 
    }
});

$('.chooseFile, .chooseFile2').bind('change', function () {
  var filename = $(this).val();  
  if (!filename) {
    $(this.parentElement.parentElement).removeClass('active');
    $(this.parentElement.querySelector(".file-select-name")).text("No file chosen..."); 
  }
  else {
    $(this.parentElement.parentElement).addClass('active');
    $(this.parentElement.querySelector(".file-select-name")).text(filename.replace("C:\\fakepath\\", "")); 
  }
});
