Primefaces Selectors: How to exclude some componen

Question

I'm using a PrimeFaces commandButton to issue an Ajax request.
I should set the update attribute so that the whole parent form be updated EXCEPT for some specific components (Let's say I've tagged them with styleClass="noupdate").
I'm using PrimeFaces 3.5, so I think PrimeFaces JQuery Selectors may help.
I tried something like this:

<!-- ...some inputs/labels to be updated here... -->
<p:overlayPanel styleClass="noupdate">
    <!-- ...some inputs/labels to be updated here... -->
    <p:commandButton id="btnDoIt" value="Do it" 
            update="@(this.closest('form') :not(.noupdate))"/>  
</p:overlayPanel>

but it doesn't work (I get a JavaScript Syntax Error).
Is there a way to get what I need?
Notice that:
1) The form id is not known because the button is part of a composite component that can be hosted by any form in different views
2) In my example the <p:overlayPanel> itself must not be updated, but any descendant component do.
3) There are more than one form in the view, and I should work on the "current" one only.

Thank you in advance to anyone can help me.

There's no such thing as this in PrimeFaces selectors. There are definitely no jQuery functions like $.closest() available in PrimeFaces selectors. It has just to be a pure jQuery-compatible CSS selector, not some JavaScript code.

<p:commandButton ... update="@(form :not(.noupdate))"/>
