c5.7.x set route to single page controller

Permalink
Hi,

in my package controller i register a route like the following:

package controller:
Route::register(
            '/{locale}/{type}/{page}',
            '\Concrete\Package\DnaPopulation\Controller\SinglePage\ContentPages::deeplink')
      ->addRequirements(array("locale" =>"de|en"));


And my ContentPages controller looks like:
public function deeplink(){
      $l =  Request::getInstance()->get('locale');
      $t =  Request::getInstance()->get('type');
      $p =  Request::getInstance()->get('page');
      $this->view();
   }
public function view(){
   echo "test";
}


this works fine but c5 shows the default theme file instead of the controllers view.

Can anybody help me?
