Patterns for Edit Modal and Page Updates

I suppose I could have one controller for the modal and another for updating the different sections.
Still, it looks like I will need to keep both controllers in the body.

I do feel like this is probably a common pattern for rails CRUD views; any recommendations would be appreciated!

modal view

<div class="modal-wrapper" data-reveal>
  <div target="edit-modal.content">
    <%= form_for venture_stage_path(@project),
                 remote: true,
                 data: {
                   action: 'ajax:success->edit-modal#onSaveSucess  ajax:success->section#onUpdate',
                   section: 'ventureStage'
                 } do |f| %>
      <!-- rendered form fields -->
    <% end %>
  </div>
 </div>

section_controller.js

export default class extends Controller {
  static targets = [
    'ventureStage',
    'location',
    'highlights',
    'oneLiner',
    'desciription',
  ];

  onUpdate(e) {
    const [data, status, xhr] = e.details;
    const currentTarget = `${e.currentTarget.dataset.section}Target`;
    this[currentTarget].innerHTML = xhr.response;
   }
}
