Thank you for all the helpful replies, I  now have a working
C::V::P::R, it produced a pdf file with contents. I was able to
received help from hobbs on #catalyst, the root cause of problem is
that C::V::P::R produces the pdf file even it cannot find the template
files, hobbs suggest that it can be file as bug but I don't have idea
how(I newbie on both Perl/Cat).

 Anyway both C::V::P::R and C::V::PDF::API2 has the same outcome it
will produce empty pdf file even it can't find the template.

e.g

on MyApp.pm:

__PACKAGE__->config('View::PDF::Reuse' => {
   INCLUDE_PATH => __PACKAGE__->path_to('root','templates') # this
will produce empty pdf
 });                             __PACKAGE__->path_to('root','src') #
after I added this it works.

on Controller:

{
      $c->stash->{list} = ['one', 'two', 'three', 'four'];
      $c->stash->{pdf_disposition} = 'attachment';
      $c->stash->{pdf_filename}    = 'receipt.pdf';
      $c->stash->{pdf_template}    = 'order/receipt.tt2';
      $c->detach( $c->view('PDF::Reuse') );

  }

actual path of template files, in this case receipt.tt2:

root/src/order/receipt.tt2
