Changes in the template do not appear in the ajax refresh

[Replicant]

When you reply to a thread and click post, the ajax calls loadNode which only calls for the content and userinfo for the new post and adds it to the thread so the entire page doesn't reload. This is also why the signature doesn't show on a new reply for the person that posted it, but anyone else loading that page will see the signature. Is there a reason the new template needs to be shown before the next refresh? Without knowing more about the functionality of the custom template, it's kind of difficult to understand why the new template would need to load since the content entry has already been performed.
