Hi,
i´m using special viewhelpers for that.
I think it is better instead of loading the js files within the controller.

The viewhelpers are very simple.
For example:

class Tx_SschFluidExtbaseHelper_ViewHelpers_Meta_AddFooterJsViewHelper 
extends Tx_Fluid_Core_ViewHelper_AbstractViewHelper {

     /**
      * renders a special title for the page
      *
      * @param string $title
      * @return string $content: The pagebrowser
      */
     public function render($file = NULL) {

         if ($file === NULL) {
             $file = $this->renderChildren();
         }
         // Makes no sense to use the DPI here
         $pageRenderer = t3lib_div::makeInstance('t3lib_PageRenderer'); 
// it is a singleton, so we get always the same instance
         /* @var $pageRenderer t3lib_PageRenderer */
         $pageRenderer->addJsFooterFile($file);
     }
}
