<p>if you set data attribute on an element using the jQuery.attr() method make sure you retreive it using using the same .attr() method. </p><p> </p><pre><code class="language-javascript">jQuery('#random-element').attr('data-test', 'testData');
// **NOT reliable
jQuery('#random-element').data('test');
// **Use this instead
jQuery('#random-element').attr('data-test');
</code></pre><p> </p>
