Drupal: Node Comments Paging displaying same 10 results

Question

<?php
    $id = $node->nid;
     $node = node_load($id);
    $node_view = node_view($node);
    $node_view['comments'] = comment_node_page_additions($node);
    print drupal_render($node_view);
?>

I have above code to print my node comments on my page--contenttype.tpl.php

And I have set the comments per page to 10.

But it is displaying the same 10 comments on second page too. And my url changes perfectly. ?page=1 etc

Can anyone help me out?
