[Catalyst] JSONP support Catalyst::Controller::DBIC::API

[Rajesh Kumar Mallah]

For the time being i have modified and solved my issue as below:

sub end : Private {
     my ( $self, $c ) = @_;

     ##
     # code for manipulating stash here
     ##

     $c->forward('serialize');

     my $cb = $c->request->params->{callback} ;

     if ($cb) {
	my $body = \$c->res->body;
	$$body = "$cb ($$body);";
	$c->res->body($$body);
     }

}
