Checkbox Groups and Radio Groups missing events

Just wondering if this is something I am doing wrong or if the events normally attached to checkbox groups and radio groups is missing.

The dmx-on:updated="" I am almost certain used to be accessible when using checkbox and radio groups in the UI, it still works if I add the code in manually, so a bit unsure.

<div class="form-group" id="input1_group" is="dmx-radio-group" dmx-on:updated="sc_get_and_set_product_card_filters.load({pcf_tag: value})">
  <legend class="col-sm-2 col-form-label">Some radios</legend>
  <div class="form-check">
    <input class="form-check-input" type="radio" value="" id="input1_1" name="input1">
    <label class="form-check-label" for="input1_1">First radio</label>
  </div>
  <div class="form-check">
    <input class="form-check-input" type="radio" value="" id="input1_2" name="input1">
    <label class="form-check-label" for="input1_2">Second radio</label>
  </div>
  <div class="form-check">
    <input class="form-check-input" type="radio" value="" id="input1_3" name="input1">
    <label class="form-check-label" for="input1_3">Third radio</label>
  </div>
</div>
