You don't need to use elem in order to get the controller, just add it as a param to the link function, and set require to ['ngModel'] in order to get the model ctrl.

 require: ['ngModel'],
 link: function (scope, elem, attrs, ctrl) {

      someObj = {val: '123'};

      scope.check = function () {
        var result = false;
        ctrl.$setValidity(result);
      };

    }
