How To Get Data Back From Angular Directive

The best way to get data back from directive is to attach a model to directive's self scope.

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

app.controller('mainController', 
                [
  '$scope', 
  function($scope){
    $scope.myObj = "Initial Value";
  }
]);

app.directive('dirName', [
  function(){
    return {
      restrict : 'A',
      scope : {
        obj : "=ngModel"
      },
      link : function(scope, element, attrs){
        scope.obj = attrs.newValue;
      }
    };
  }
]);
