I have a page reference method in the  APex controller which is  exposed as rest api.

The page reference method gets invoked and below is the syntax:

  PageReference myVFPage = new PageReference('/apex/VFPageName=' + vfPageId);
               myVFPage.setRedirect(true);
For the Pagereference method , I had set the return type as VFPageName.

The method is getting executed with no errors how ever the VF page is not loading.
How can I make sure the VF Page gets loaded and the Java Script events gets fired during the page load.

Thank You
