custom add note meta box with add button in wordpress

Question

I'm making a custom note meta box for plugin, and I have a note box input and one 'add' button in the box with. The button saves the text but does not move the text to the notepad but instead stays in the Box but saved, I'd like the text when saved to move to the note pad

    else {
            print '<hr />';
        }
        print '<div id="ppn_add_post_note" style="margin: 10px 0 10px 0;">';
        print '<label for="ppn_post_note">' . __('Add note:', 'peters_post_notes') . '</label><br />';
        print '<textarea rows="3" cols="30" name="ppn_post_note" id="ppn_post_note" style="width: 99%">
'.get_post_meta($post->ID, 'ppn_post_note', true).'
</textarea><br /><br />';
        print '<label><input type="checkbox" name="ppn_private" /> ' . __('Private note', 'peters_post_notes') . "</label>\n";
        print '</div>
<div style="text-align: right">
<input type="submit" value="Save" id="save_note">value="Add" tabindex="5" accesskey="p">

</div>
