title: Woocommerce: variation select not triggered correct
body: <p>I see another topic with an analog question, but not find answer. I have a custom input view for Variations. I want to trigger stock selection when variations change (for change price, image, and more). When I use stock select variation work correctly. But when I programming change value of select and triggered it &quot;change&quot; then nothing works.</p>
  <p>My custom input</p>
  <pre><code>&lt;input class=&quot;radio-custom input_attribute&quot; select_id=&quot;&lt;?=$attribute_name?&gt;&quot; name=&quot;input_attribute_&lt;?=$attribute_name?&gt;&quot; value=&quot;&lt;?=$option?&gt;&quot; type=&quot;radio&quot;&gt;
  </code></pre>
  <p>My Jquery code</p>
  <pre><code>$(&quot;.input_attribute&quot;).change(function (){
          $(&quot;select#&quot; + $(this).attr(&quot;select_id&quot;)).val($(this).val()).trigger(&quot;change&quot;);
      });
  </code></pre>
  <p>What do I need to be triggered another selection?</p>
