[jQuery] jquery documentation of exlusion pseudo-class


according to jquery documentation I should be able to select an
element that is NOT something, i.e. exclusion.
DOM:
<div>hello <span>there, how are</span> you?</div>
JQUERY SELECTOR:
$('DIV :not(SPAN)')
SHOULD RETURN:
<div>hello you?</div>
right? well, it's not happening for me... what am I dogin wrong?
