[jQuery] Checking each div to see if it contains specific text

[Nic Hubbard]

I have a list of container divs that have children.  I want to check
for specific text in one child element, and if that is found, then
hide another child element.  For some reason what I have is not
working:

$('.exhibition_item_body').each(function () {
        if ($(this).children(".checkReception:contains('--:--:--')")) {
                $(this).children('.reception').hide();
        }
});

The divs look like:

<div class="exhibition_item_body">
<h3><a href="#">Jane Maxwell</a></h3>
<p class="checkReception" style="display: none;">2009-03-05 --:--:--</
p>
<p class="date">Mar 5 - Mar 31, 2009</p>
<p class="reception" style="display: none;">Reception Mar 5, 2009 5 -
7 PM</p>
<p class="location">San Francisco</p>
<p class="exhibition_status">Previous Exhibition</p>
</div>
<div class="clear"/>
</div>
