Why do not work dots in the slider?

Question

UIkit

Here is the slider code. It displays correctly. All right. The dots appeared, but when you click on them, nothing happens. I work with Uikit 2. I seem to be doing everything according to the documentation, but the result is not the same. Maybe someone knows what's the matter and how to make the slider points function?

<!-- slider -->
<div class="uk-slidenav-position" data-uk-slider="{autoplay:true}">
    <div class="uk-slider-container">
        <ul class="uk-slider uk-grid-width-medium-1-1"> 
  			<li><img src="storage/sons/pic-slider-1.jpg" width="100%" height="100%" alt="slider picture"></li>
            <li><img src="storage/sons/pic-slider-2.jpg" width="100%" height="100%" alt="slider picture"></li>
            <li><img src="storage/sons/pic-slider-3.jpg" width="100%" height="100%" alt="slider picture"></li>
            <li><img src="storage/sons/pic-slider-4.jpg" width="100%" height="100%" alt="slider picture"></li>
        </ul>
        <ul class="uk-dotnav uk-dotnav-contrast uk-position-bottom uk-flex-center">
            <li data-uk-slideshow-item="0"><a href="#">Item 1</a></li>
            <li data-uk-slideshow-item="1"><a href="#">Item 2</a></li>
            <li data-uk-slideshow-item="2"><a href="#">Item 3</a></li>
            <li data-uk-slideshow-item="3"><a href="#">Item 4</a></li>
        </ul>
    </div>
</div>

Answer 1

dotnav.css included? if you use a slideshow and not a slider, will it work?
