Show same comments on all posts

Im currently making a template and the comment template show the same comment on all blog posts why ? Im using bootstrap if some one want to know.

Code in functions.php

function mytheme_comment($comment, $args, $depth) {

    $GLOBALS['comment'] = $comment;
    extract($args, EXTR_SKIP);

    $avatar = preg_replace('#.*src="([^\"]+)".*#', '\1', get_avatar($comment,$size='48'));

   ?>

   <div class="media" id="comment-<?php comment_ID() ?>">

    <div class="media-left">

      <a href="<?php echo htmlspecialchars(get_comment_link($comment->comment_ID)) ?>">

        <img class="media-object img-rounded" src="<?php echo $avatar; ?>" style="width:42px;">

      </a>

    </div>

    <div class="media-body">

      <h5 class="media-heading"><?php printf(__('%1$s at %2$s'), get_comment_date(),  get_comment_time()) ?>, <?php printf(__('<cite class="fn">%s</cite> <span class="says">says:</span>'), get_comment_author_link()) ?></h5>

      <?php comment_text() ?> 

      <p>

        <?php edit_comment_link(__('(Redigera) - '),'  ','') ?> <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?>

      </p>

    </div>

  </div>

<?php
