After attaching permissions to role still getting false in can() method

I am using entrust to manage roles and permission in my application. I am having trouble to call method attachPermission() on user. Then I tried it another way I assigned all permissions to a role. When I sign-in using that user I get false for every permission from can() method.

I can see all permissions assigned to a role. But even registering a middle-ware or calling method;

Entrust::routeNeedsPermission('admin/countries*','countries-list', Redirect::to('/admin')); Is returning false means redirects me to /admin. I don't know what's wrong with it or It is some kind of compatibility issue with laravel 5.1.
