Subscription not working at the time user registration. I echoed stripe token which is perfect. but some how the subscription not working. this is my controller code:

 public function postStore() {


        $sid = Input::get('id');

        $rules = array(
            'first_name' => 'required',
            'last_name' => 'required',
            'email' => 'required'
        );

        if (isset($sid)) {
            $rules['password'] = 'confirmed|min:6';
        } else {
            $rules['password'] = 'required|confirmed|min:6';
        }

        $validation = Validator::make(Input::all(), $rules);

        if (!$validation->passes()) {
            if (isset($sid)) {
                return Redirect::to('users/edit/' . $sid)->withErrors($validation)->withInput();
            } else {
                return Redirect::to('users/create')->withErrors($validation)->withInput();
            }
        }

        $first_name = Input::get('first_name');
        $last_name = Input::get('last_name');
        $email = Input::get('email');
        $password = Input::get('password');
        $role = 4;
        $activated = true;
        $subscriptiont_type = Input::get('subscriptiont_type');

        if (isset($sid)) {
            // Edit existing
            try {
                $user = Sentry::findUserById($sid);

                $user->email = $email;
                if ($password != '') {

                // Assign the group to the user
                if ($old_group->id != $new_group->id) {
                    $user->removeGroup($old_group);
                    $user->addGroup($new_group);
                }
