• Swiper Version: 3.4
• Platform/Target and Browser Versions: Version 52.0.2743.116 Built on Ubuntu , running on Ubuntu 16.04 (64-bit)

  What you did

Upgrading to version 3.4 the function to customize paginations bullets does not work :

var swiper = new Swiper('.swiper-slider', {
        nextButton: '.swiper-button-next',
        prevButton: '.swiper-button-prev',
        spaceBetween: 30,
        autoplay: 8000,
        paginationType:'bullets',
        pagination: '.swiper-pagination',
        paginationClickable: true,
      paginationBulletRender: function (index, className) {
            return '<span class="' + className + '">' + (index + 1) + '</span>';
        }
}

Expected Behavior

the function should return 'swiper-pagination-bullet' as className and the index of each single slide

Actual Behavior

[object object ] is returned as index, and a number(the index?) as className
