AngularJS communication between controller and directive

Question

How to get some data from controller and use it inside directive thats not a problem. But I stack with such situation when I need get data from directive and use it in my controller.

For exmpl:

My controller:

function MyController($scope, $location, myDirective) {
    "use strict";

    // here i need use scope.importantValue and create() method from directive

}

My directive:

        .directive("myDirective", function() {
"use strict";
return {
    restrict: 'A',
    template: '<div></div>',
    replace: true,
    scope: {
        data: '=',
    },
    link: function(scope, elm) {
        scope.importantValue = "value";

        function create() {
            console.log("Directive works...");
        }

};
})

How I can use variables or/and methods from directive inside my controller?

We moved to directive some part of code that similar for few views and this directive contains some variables that can be used in other parts of project. I wanna know is it posible to use this variables in a controller or not? — Lugaru

The simplest way to accomplish this is to make both your controller and directive get importantValue and create() from a service.

angular.module(/* Your module */).service('sharedData', function () {
    return {
        importantValue: "value",
        create: function () {
            console.log("Directive works...");
        }
    };
});

Now you can inject sharedData into your directive and controller and access importantValue and create() from either place.
