Function not showing up in child theme WordPress

I was having problems with functions in the Aaron child theme in WordPress. I had part of my problem answered in Overwrite parent functions in child function.php WordPress but I couldn’t get the logo to work as a bigger size. I eliminated a lot of code in order to narrow down and find the problem. And what I found is that the function in child theme wasn’t showing up in WordPress. This is the function:

/* Site Logo */
function add_site_icon_support() {
  $args = array(
    'header-text' => array(
      'Site Title Here',
      'Your site description goes here.',
    ),
    'size' => 'medium',
  );
  add_theme_support( 'site-logo', $args );
}
add_action( 'after_setup_theme', 'add_site_icon_support' );

I tested it out by adding it to the functions.php in parent theme and it works. Therefore, I was wondering how to make it work in the child theme?

Does it have something to do with this function in parent theme?

function aaron_setup() {
  /*
   * Make theme available for translation.
   * Translations can be filed in the /languages/ directory.
   * If you're building a theme based on aaron, use a find and replace
   * to change 'aaron' to the name of your theme in all the template files
   */
  load_theme_textdomain('aaron', get_template_directory() . '/languages');
  // Add default posts and comments RSS feed links to head.
  add_theme_support('automatic-feed-links');
  add_theme_support('woocommerce');
  add_theme_support('jetpack-responsive-videos');
  add_editor_style();
  add_theme_support('post-thumbnails');
  add_image_size('aaron-featured-posts-thumb', 360, 300);
  add_theme_support('title-tag');
  register_nav_menus(array(
    'header' => __('Primary Menu', 'aaron'),
    'social' => __('Social Menu', 'aaron'),
  ));
  /*
   * Switch default core markup for search form, comment form, and comments
   * to output valid HTML5.
  */
  add_theme_support('html5', array('search-form', 'comment-form', 'comment-list', 'gallery', 'caption'));
}
endif; // aaron_setup
add_action('after_setup_theme', 'aaron_setup');

Since both have the same hooks.
