angularjs - Using "require" in Directive to require a parent Controller

Question

I try to "require" a parent controller (not directive) but AngularJS returns an exception. The code is like this:

JS

app.controller("myController", function ($scole) {
    ...
});

app.directive("myDirective", function ($q) {
    return {
        require: "^myController",
        template: "",
        link: function (scope, element, attrs, myCtrl) {
            ...
        }
    };
});

HTML

<div ng-controller="myController as myCtrl">
    ...
        <div my-directive>...</div>
    ...
</div>

Error

Error: [$compile:ctreq] Controller 'myController', required by directive 'myDirective', can't be found!

Why?
Maybe, require property must be reference to a controller of directive?

Thanks

Require is of using other directives controllers in another directive , please refer the below example

var App =  angular.module('myApp',[]);

//one directive

App.directive('oneDirective',function(){

  return {
      restrict: 'E',
      controller:function($scope){

       $scope.myName= function(){
            console.log('myname');
          }

         }
    }

});

   //two directive

  App.directive('twoDirective',function(){

  return {
      require:'oneDirective' //one directive used,
      link : function(scope,ele,attrs,oneCtrl){
         console.log(oneCtrl.myName())
     }

   }

  })
