curt2008 on "Add nextpage tag dynamically using Plugin Shortcode"

Hi Guys,

I'm trying to add the <!--nextpage--> tag dynamically using a Shortcode call, but all it's actually doing is adding it as an HTML Comment instead of rendering it as pagination links, here's my code that I'm attempting to do;

public function __construct() {
     add_shortcode('CONTINUED', array(&$this, 'continued_handle'));
}

public function continued_handle() {
    global $post;
    return $this->your_post_split($post);
}

public function your_post_split($content) {
    $output = '<div>In page 1</div>';
    $output .= '<!--nextpage-->';
    $output .= '<div>In page 2</div>';
    return $output;
}

If anyone can give me any advice as to how I can get it to render the <!--nextpage--> tag as Pagination links I'd be highly appreciated!
