Save changes to tinymce inline editor in rails app? - ruby-on-rails

Question

I'm trying to save updates made in the inline tinymce editor in my rails app, but I don't know how to do it exactly as I want. I want the inline editor to be able to save while the view is 'html_safe'. I can save it fine if the form area is a text area (i.e. <div class="editor"><%= form.text_area :content %></div>), but I want to have the view in inline editor format so you can see your changes on the fly.
In the logs, it looks like the invitation params are closing before it's including the changes needed. How do I do this so that the inline editor changes are saved correctly?
Note: Everything else is working correctly, except the changes to the <%= #invitation.content %> are not being saved.
View:
<%= form_with(model: #invitation, local: true) do |form| %>
<%= form.hidden_field :event_id, value: #event.id %>
<div class="editor"><%= #invitation.content.html_safe %></div>
<script type="text/javascript">
tinyMCE.init({
selector: '.editor',
menubar: false,
inline: true,
plugins: "save",
toolbar: "save"
});
</script>
<% end %>
And my output from the log is:

And my controller is a basic object controller:
