bindToController in ng 1.2.x

example.js

// this example shows how to write a helper to get something like bindToController
// in angular 1.2.x
// this example is incomplete and mostly meant to illustrate the technique

angular.module('myModule', []).directive('myDir', function () {
  return bindToController({
    scope: {
      foo: '='
    },
    controller: 'MyController',
    controllerAs: 'myCtrl'
  });
});

// this isn't complete, but it is a good starting point.
// for isntance, it doesn't really handle all types of bindings.
function bindToController (ddo) {
  var link = ddo.link || angular.noop;
  ddo.link = function (scope, element, attrs, ctrls) {
    
    // watch $scope.foo and copy changes to $scope.myCtrl.foo
    Object.keys(ddo.scope).forEach(function (prop) {
      scope.$watch(prop, function (newVal) {
        scope[ddo.controllerAs][prop] = newVal;
      });
    });

    // run original link fn
    return link(scope, element, attrs, ctrls);
  };
}

bindToController doesn't return ddo
