Revisioning links not appearing when using custom node templates

Thanks for helping me out! In fact, i don`t want to theme the links rather making them appear on my node. I`m using a custom node template file for my news, called node-news_article.tpl.php. This is how it looks like:

<div id="node-<?php print $node->nid; ?>" class="node<?php if ($sticky) { print ' sticky'; } ?><?php if (!$status) { print ' node-unpublished'; } ?> clear-block">
  <?php if ($page == 0): ?>
    <h2><a href="<?php print $node_url ?>" title="<?php print $title ?>"><?php print $title ?></a></h2>   
  <?php endif; ?>   
  <?php print $picture ?>     
  <div class="content">  
  <div id="news-head-container">
  <div id="news-head-image-container">
  <div id="news-head-image">
  <?php print $field_news_image[0]['view']; ?>
  </div> 
  </div>
  <div id="news-head-teaser-container">
  <div id="news-head-teaser-created">
  <?php print format_date($node->created, 'custom', "d.m.Y"); ?> 
  </div>
  <div id="news-head-teaser">
  <?php print $field_news_teaser[0]['view']; ?>
  </div>
  </div>
  </div>
  <div id="news-body">
  <?php print $node->content['body']['#value']; ?>
  </div>
      <div id="news-files">
  <?php print $node->content['files']['#value']; ?>
  </div>
   <?php if (!empty($field_nodereference)): ?>
 <?php print $node->content['field_nodereference']['#children']; ?>
  <?php endif; ?> 
  
  </div> 
<?php if ($links): ?>
    <?php if ($picture): ?>
      <br class='clear' />
    <?php endif; ?>
  <div class="links"><?php print $links ?></div>
<?php endif; ?>
</div>

I also appended a screenshot called "Custom_Node_Template.jpg" to show how it looks like in the browser. As you can see, the links to edit, publish or revert the current revision are not showing.
Now, if i delete the node-news_article.tpl.php file, the standard node.tpl.php is used.

<div id="node-<?php print $node->nid; ?>" class="node<?php if ($sticky) { print ' sticky'; } ?><?php if (!$status) { print ' node-unpublished'; } ?> clear-block">
  <?php if ($page == 0): ?>
    <h2><a href="<?php print $node_url ?>" title="<?php print $title ?>"><?php print $title ?></a></h2>
  <?php endif; ?>
  <?php print $picture ?>
  <div class="content">
  <?php print $content ?>
  </div>
<?php if ($links): ?>
    <?php if ($picture): ?>
      <br class='clear' />
    <?php endif; ?>
  <div class="links"><?php print $links ?></div>
<?php endif; ?>
</div>

Now, the links appear above the news text right below the tab bar. See screenshot Standard_Node_Template.jpg. Is there any chance to get this working with the custom node template file?
Besides, sorry for using a not so distinct title.

Best regards
Stephan
