How to load angularjs directive use $injector

I'm trying to use directive from other modules that is loaded by angular.injector but angular can't understand directives that is in other_module.
In my main file, I declare my module.

  angular.module('blockApp', []).directive('', []);

In second file, I try to add angularCharts as dependency:

  var otherBlock = angular.module('blockApp');
  otherBlock.run(function() {
      angular.injector(['ng', 'angularCharts']);
  });

Then I use angularCharts's directives but angularjs can't identify them. I know we should add dependent modules when we declare module but it is special case.

here's a plnkr http://plnkr.co/edit/Q5oD65wSvBAemf5BCDL7?p=preview

In this case you can use $compile (you still need a $scope from the example, but $compile pretty much answers your question I guess),

    var $compile = chartsInjector.get("$compile");
    console.log("$compile=",$compile);

    var chartsDirective = $compile("<div charts></div>");
    console.log(chartsDirective);

...

  var blockapp = angular.module('blockApp', []); 
  blockapp.run(function(){
    // create a new injector
    var chartsInjector = angular.injector(['ng', 'angularCharts']);
    console.log("chartsInjector=",chartsInjector);

    var $compile = chartsInjector.get("$compile");
    console.log("$compile=",$compile);

    var chartsDirective = $compile("<div charts></div>");
    console.log(chartsDirective);
  })

note that you will be creating multiple injectors here.

injector 1) created by ng-app

<body ng-app="blockApp">

injector 2) created by angular.injector()

var chartsInjector = angular.injector(['ng', 'angularCharts']);

whole code

<!DOCTYPE html>
<html>

  <head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
    <script type="text/javascript">
      // creating the angularcharts
      angular.module('angularCharts', []).directive('charts', function(){
        return function(){}
      }); 

      // creating blockapp
      angular.module('blockApp', []).directive('', []); 

      // retrieving the created blockapp
      // NOTE! ng-app will create a new injector for blockapp 
      var blockapp = angular.module('blockApp', []); 
      blockapp.run(function(){
        // create a new injector
        var chartsInjector = angular.injector(['ng', 'angularCharts']);
        console.log("chartsInjector=",chartsInjector);

        var $compile = chartsInjector.get("$compile");
        console.log("$compile=",$compile);

        var chartsDirective = $compile("<div charts></div>");
        console.log(chartsDirective);
      })

    </script>
  </head>

  <body ng-app="blockApp">

  </body>

</html>
