How does the hook 'elementor/element/after_section_end' render values in the preview window?

[WebsiteDons]

I injected fields to the elementor core columns using the hook, but the result is rendered only on the frontend and not in the preview window. What hook is need to get the task done?

The coding to add the fields

add_action('elementor/element/after_section_end', function($element,$section_id, $args)
{
  $name = $element->get_name();
  if( 'section_advanced' === $section_id )
  {
    if( 'column' === $name )
    {
      $element->start_controls_section('ctrl_section', [
        'label'=>'Set Column As Accordion',
        'tab'=> \Elementor\Controls_Manager::TAB_CONTENT
      ]);

        $element->add_control('col_acctitle',[
	  'type' => \Elementor\Controls_Manager::TEXT,
	  'label' => 'Title',
	  'label_block'=>true
	]);
        // more fields here

      $element->end_controls_section();
    }
  }
},10,3);

Front end render

add_action('elementor/frontend/column/before_render', function($element) 
{
  $v = (object)$element->get_settings_for_display();

  if( isset($v->col_accordion) && $v->col_accordion == 'yes' ) 
  {
    // other values processed here
    // title output
    echo '<h3 class="tab-handle" style="">'.$v->col_acctitle.'</h3>';
  }
});

Front end display

The output is correct, but none of this shows in the elementor preview window

The following hook resolved the display.

add_action('elementor/column/print_template', function($template, $element) 
{
  ob_start();
  ?>
    <#
      var maaxAcc = 'yes' === settings.col_accordion ? true : false;
      if( maaxAcc ) { #>
        <h3>the title</h3>
      <# } #>
  <?php
  $acc = ob_get_clean();

  return $acc . $template;
}

Awesome, found your post because I had the same issue: how to render the new settings in the backend. Your code works fine 👍
Do you have an idea on how to add a class to the existing wrapper? I'm extending the container with elementor/container/print_template and I can add custom html tags like you did. But I would like to add custom class to the instead of adding html elements like you did. Any idea?
