Meta box in links / Wordpress

Question

Is there a way to save meta box value when it's added to links? Here is my code:

<?php
/*
Plugin Name: Link Date
Plugin URI: http://
Description: Adds links date field.
Version: None
Author: Auth
Author URI: http://
*/

add_action( 'add_meta_boxes', 'link_date_add' );
function link_date_add()
{
    add_meta_box( 'link-date-meta-box', 'Link Date', 'link_date', 'link', 'normal', 'high'     );
    }


function link_date( $post )
{
    $values = get_post_custom( $post->ID );
    $date = isset( $values['link_date_text'] ) ? esc_attr( $values['link_date_text'][0] ) : '';
    wp_nonce_field( 'my_link_date_nonce', 'link_date_nonce' );
    var_dump($post);
    ?>
<p>
    <label for="link_date_text">Link Date</label>
    <input type="text" name="link_date_text" id="link_date_text" value="<?php echo $date; ?>" />
</p>

<?php
}


add_action( 'save_post', 'link_date_save' );
function link_date_save( $post_id )
{
    if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;

    if( !isset( $_POST['link_date_nonce'] ) || !wp_verify_nonce( $_POST['link_date_nonce'], 'my_link_date_nonce' ) ) return;

    if( !current_user_can( 'edit_post' ) ) return;

    $allowed = array(
        'a' => array(
        'href' => array() // and those anchords can only have href attribute
    )
);


if( isset( $_POST['link_date_text'] ) )
    update_post_meta( $post_id, 'link_date_text', wp_kses( $_POST['link_date_text'], $allowed ) );


}

?>

This code works, when post type changed to 'post', but for some reason it doesn't save data as 'link' type of post.

I saved some data from this field when post type was set as 'post', then updated the post type in code to 'link', and additionally updated the database (wp_postmeta) replacing the id with the id of link. Then this data was displayed in meta box in links, but still, bot able to update value of this metabox.

The answer is to use add_action('edit_link','save_data') and add_option('name_of_option') instead of add_post_meta view full results here MetaBox Links
