如何激活bootstrap模式next和back按钮

Question

我正在尝试升级此多步骤表单，以便后面和下一个按钮位于此模式的页脚中。我该怎么办呢？ （即RED中的下一个按钮） - 点击此按钮不起作用。

谢谢

$(document).ready(function() {
  var navListItems = $('div.setup-panel div a'),
    allWells = $('.setup-content'),
    allNextBtn = $('.nextBtn'),
    allPrevBtn = $('.prevBtn');

  allWells.hide();

  navListItems.click(function(e) {
    e.preventDefault();
    var $target = $($(this).attr('href')),
      $item = $(this);

    if (!$item.hasClass('disabled')) {
      navListItems.removeClass('btn-primary').addClass('btn-default');
      $item.addClass('btn-primary');
      allWells.hide();
      $target.show();
      $target.find('input:eq(0)').focus();
    }
  });

  allPrevBtn.click(function() {
    var curStep = $(this).closest(".setup-content"),
      curStepBtn = curStep.attr("id"),
      prevStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().prev().children("a");

    prevStepWizard.trigger('click');
  });

  allNextBtn.click(function() {
    var curStep = $(this).closest(".setup-content"),
      curStepBtn = curStep.attr("id"),
      nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next().children("a"),
      curInputs = curStep.find("input[type='text'],input[type='url']"),
      isValid = true;

    $(".form-group").removeClass("has-error");
    for (var i = 0; i < curInputs.length; i++) {
      if (!curInputs[i].validity.valid) {
        isValid = false;
        $(curInputs[i]).closest(".form-group").addClass("has-error");
      }
    }

    if (isValid)
      nextStepWizard.removeAttr('disabled').trigger('click');
  });

  $('div.setup-panel div a.btn-primary').trigger('click');
});
