Make sure when declaring your regions that you have used different names for

<% Jifty->web->region( name => 'region-1', path => '/fragment/test' ); %>
<% Jifty->web->region( name => 'region-2', path => '/fragment/test' ); %>

You can reuse paths all you want in your various regions, but region names
should not be reused unless they're nested in separate regions. (I.e., if
/fragment/test has a nested region with the same name in each, that's fine).

I don't know if that's your problem or not, but that's what it sounds like
to me.

You onclick handler should use the region=> parameter to specify which
region is targeted. This could also be your problem.
