When you do

  __PACKAGE__->config(foo => 'bar');

in your controller, that setting never reaches the application configuration.

Settings in your configuration file are available via $c->config, or [%
c.config %] in TT. You can configure components (read: models, views and
controllers) from this file via (example in YAML):

    ERROR: 'whatever'

The 'View::TT' configuration will be pushed to your 'MyApp::View::TT'
component. It will there be merged with the local component configuration
directly in the package. E.g.

    TEMPLATE_EXTENSION => '.html',

The merged configuration will be usually (if not implemented otherwise) in
the controller instance directly. So the best way might be

  package MyApp::View::TT
  sub the_config_you_want {
      my ($self) = @_;
      return $self->{the_config_you_want};

and then in the template

  [% c.view('TT').the_config_you_want %]
