Semantic UI Radio Buttons do not check when clicking the label
<p>As the title says, the radio buttons do not check when the label (tex) is clicked. However this seems to work fine on Semantic's site.</p>

<p>Semantic UI Documentation with working radio buttons: <a href="http://semantic-ui.com/modules/checkbox.html" rel="noreferrer">http://semantic-ui.com/modules/checkbox.html</a></p>

<p>The following example code is straight from the Semantic UI Documentation above:</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.1.8/semantic.min.css" rel="stylesheet"/&gt;
&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.1.8/semantic.min.js"&gt;&lt;/script&gt;
&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;

&lt;div class="ui form"&gt;
  &lt;div class="grouped fields"&gt;
    &lt;label&gt;How often do you use checkboxes?&lt;/label&gt;
    &lt;div class="field"&gt;
      &lt;div class="ui radio checkbox"&gt;
        &lt;input type="radio" name="example2" checked="checked"&gt;
        &lt;label&gt;Once a week&lt;/label&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="field"&gt;
      &lt;div class="ui radio checkbox"&gt;
        &lt;input type="radio" name="example2"&gt;
        &lt;label&gt;2-3 times a week&lt;/label&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="field"&gt;
      &lt;div class="ui radio checkbox"&gt;
        &lt;input type="radio" name="example2"&gt;
        &lt;label&gt;Once a day&lt;/label&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="field"&gt;
      &lt;div class="ui radio checkbox"&gt;
        &lt;input type="radio" name="example2"&gt;
        &lt;label&gt;Twice a day&lt;/label&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>

<p>How can I fix this?</p>

<p>Edit: Apparently I need some javascript for the radio buttons as is mentioned here: <a href="http://semantic-ui.com/modules/checkbox.html#/usage" rel="noreferrer">http://semantic-ui.com/modules/checkbox.html#/usage</a>. I'm having trouble finding the minimum required code for a working radio button/checkbox though.</p>
