How to update_comment_meta from checkbox in comments_custom_column?

Question

I've added a custom column to the edit-comments.php page called "Tips". This column includes a checkbox.

My question is when you click on the checkbox, how do you trigger the "update_comment_meta" function?

This is what I have done, and all I receive is a "function comment_edit_tip is not defined" error.

Any ideas?

functions.php file :

// create the tips column in the admin comments section
function tips_add_comments_columns( $my_cols ) {

    $tip_columns = array(
        'comment_tip' => 'Tip',
    );

    // set the column so it displays in the third spot
    $my_cols = array_slice( $my_cols, 0, 3, true ) + $tip_columns + array_slice( $my_cols, 3, NULL, true );

    // return the result
    return $my_cols;
}
add_filter('manage_edit-comments_columns', 'tips_add_comments_columns');


// display if comment is a tip or not in the column
function tips_add_comment_columns_content( $column, $comment_id ) {
    if ($column == 'comment_tip')
    {
        $tip = get_comment_meta($comment_id, 'tip', true);
        if ($tip == 'yes')
        {
            echo '<div><input type="checkbox" id="' . $comment_id . '" onclick="comment_edit_tip(' . $comment_id . ', \'yes\')" checked /> <span class="message">Yes</span></div>';
        }
        else
        {
            echo '<div><input type="checkbox" id="' . $comment_id . '" onclick="comment_edit_tip(' . $comment_id . ', \'no\')" /> <span class="message">No</span></div>';
        }
    }
}
add_action('manage_comments_custom_column', 'tips_add_comment_columns_content', 10, 2);


// update the comment meta
function comment_edit_tip($comment_id, $value) {
    if ($value == 'yes')
    {
        update_comment_meta($comment_id, 'tip', 'yes');
    }
    if ($value == 'no')
    {
        update_comment_meta($comment_id, 'tip', 'no');
    }
}
