Rename Next Post & Previous Post

Hi,

I try to rename the Next Post & Previous Post button by the title of the post.
I created a Virtue child theme and change the entry-post-links.php as following with %link and %title. But no change. Could you please help? thanks!

<div class=”kad-post-navigation clearfix”>
<div class=”alignleft kad-previous-link”>
<?php previous_post_link(‘%link’,’%title’); ?>
</div>
<div class=”alignright kad-next-link”>
<?php next_post_link(‘%link’,’%title’); ?>
</div>
</div> <!– end navigation –>
