Bootstrap Radio Buttons not toggling
<p>I'm currently trying to setup some bootstrap radio buttons. The code looks like the one from the Bootstrap examples, but the event is not fired to set a label active.
Here's my code:</p>

<pre><code>&lt;div id="mergeType" class="btn-group"&gt;
    &lt;label for="radio1" class="btn btn-sm btn-success"&gt;
        &lt;input type="radio" name="mergeType" id="radio1" value="OVW"&gt;Überschreiben
    &lt;/label&gt;
    &lt;label for="radio2" class="btn btn-sm btn-success"&gt;
        &lt;input type="radio" name="mergeType" id="radio2" value="ADD"&gt;Hinzufügen
    &lt;/label&gt;
    &lt;label for="radio3" class="btn btn-sm btn-success"&gt;
        &lt;input type="radio" name="mergeType" id="radio3" value="KEE"&gt;Gefunde behalten
    &lt;/label&gt;
    &lt;label for="radio4" class="btn btn-sm btn-success"&gt;
        &lt;input type="radio" name="mergeType" id="radio4" value="DEL" checked="checked"&gt;Gefundene entfernen
    &lt;/label&gt;
&lt;/div&gt;
</code></pre>

<p>I don't do anything with the radio buttons in the JavaScript backend. What might be the issue here?</p>
