Save $common:
$self->param('common',$common);
Get $common in teardown():
my $common = $self->param('common');

It seems like the desire for this arises because although the teardown
is present at the place in flow you want, it's not doing what you want.
I think using param() can solve that.

This code isn't clear. It certainly wouldn't past "use strict". It
appears $template and $common are at least package scope variables.
Passing data through param() is the recommended alternative if a smaller
scope doesn't cut it for you.
