Show child category name ONLY inside the loop

Question

The code below works for my posts from Custom Post Type(called Sermon) which is displaying the child category name only with its links.

<?php
  $categories = get_the_category();
  if ( ! empty( $categories ) ) {
  echo '<a href="' . esc_url( get_category_link( $categories[0]->term_id ) ) . '">Child Category : ' . esc_html( $categories[0]->name ) . '</a>';
  }
?>

But it doesn't work when I reuse it for my posts from post type itself(News category). It keeps showing the parent category(News), unless I unchecked it so it displays the child category only(like entertainment, politics, etc.).

Any help would be appreciated. Thanks!

I have tried changing the object names but it really keeps showing the parent tag on some posts. I hope someone could help me create a function for this one if this is not achievable without using custom function. :) — Randy, Oct 11 '16 at 07:58

I've solved my problem with this custom function I found online and modified a little bit to meet my requirements.

function the_category_children($slug=""){
  $separator = ', ';
  $output = '';
  if($categories       = get_the_category()):
    if($slug_category   = get_category_by_slug($slug)):
      foreach($categories as $category):
        if (cat_is_ancestor_of($slug_category, $category)):
          $output .= '<a href="' . esc_url( get_category_link( $category->term_id ) ) . '">' . esc_html( $category->name ) . '</a>' . $separator;
        endif;
      endforeach;
      echo trim( $output, $separator );
    endif;
  endif;
}

And calling this function the_category_children('category_name') inside the loop(content.php). ^_^
