here we go again... :-)
I replied to a similar question regarding specifying an ID inside of
a class a few days ago.
same thing applies to ID inside an ID...
This paragraph from the reference section of the upcoming Learning
jQuery book might help explain why someone would want or need to
preselect a class first. It discusses specifying a tag name rather
than a class, but the same principle applies:
It might not be immediately clear why someone might want to
specify a tag name associated with a particular id, since that id
needs to be unique anyway. However, some situations in which parts
of the DOM are user-generated may require a more specific
expression to avoid false positives. Furthermore, when the same
script is run on more than one page, it might be necessary to
identify the id's element, since the pages could be associating
the same id with different elements. For example, Page A might
have <h1 id='title'> while Page B has <h2 id='title'>.
Hope that makes sense.

More importantly, why are you using two ID's?
Remember, ID's are supposed to be unique, so just $('#bar') should
work.
If your ID's aren't unique, I highly suggest you change them to
classes.
