Is Form Analytics required to track form submissions?

Support & Bugs

I don’t seem to be getting any output in the Events area of the Dashboard. Perhaps I’m doing something incorrectly?

I’ve added the following to my <script> block below the Piwik tracking code :

const form = document.querySelector('.my-form');
form.addEventListener('submit', () => {
  _paq.push(['trackEvent', 'MyFormSubmitted', 'submit']);
});

And the following HTML:

<form 
  class="my-form" 
  data-track-content
  data-content-ignoreinteraction
  data-content-name="myForm"
  method="POST"
  action="//mailchimp/post/url/stuff">
...
</form>

I don’t know what I can try to troubleshoot…
