Commontator with Trix

Good day robots,

I'm trying to implement the Trix editor as the default editor for Commontator's comments.

The default Commontator view is defined as follows in app\views\commontator\comments\_form.html.erb:

<%= form_for([commontator, thread, comment],
             remote: !no_remote) do |f| %>
<div class="comment_form_field">
    <%= f.text_area :body, rows: '7' %>
    <%= javascript_tag('Commontator.initMentions()') if Commontator.mentions_enabled %>
</div>
<% end %>

So I get that I need to replace that text_area for the Trix default tag: <trix-editor input="???"></trix-editor> not sure what to put into the input parameter.

The generated HTML for the above form_for is as follows;

<form class="new_comment" id="new_comment" action="/commontator/threads/1/comments" accept-charset="UTF-8" data-remote="true" method="post">

<div class="comment_form_field">
    <div class="field_with_errors">
        <textarea rows="7" name="comment[body]" id="comment_body" spellcheck="false"></textarea>
    </div>
</div>

<div class="comment_form_actions">
    <input type="submit" name="commit" value="Post Comment" data-disable-with="Post Comment">
    <input type="submit" name="cancel" value="Cancel" data-disable-with="Cancel">
</div>

</form>

Any ideas? cheers!
