Updating select2 via angular controller?

I'm attempting to use Angular's $http directive to pull a list of tags from a server, and use that to populate a select2 select. My code looks like this:

    var samplePage = angular.module('samplePage', ['ui.select2']);

    samplePage.controller('sampleController', function($scope, $http) {
        console.log($scope);
        // THIS WORKS
        $scope.tags = ['a', 'b', 'c'];
        $http.get('angular.html').success(function(rc) {
            console.log($scope);
            // THIS DOES NOT WORK
            $scope.tags = ['d', 'e', 'f'];
        })
    });

    angular.bootstrap(document, ['samplePage']);

However, the "tags" is not being updated! Or, rather, "tags" is being updated but the select2 widget does not seem to be binding properly.

The view looks like this:

<div ng-app="samplePage">
    <div ng-controller="sampleController">
    <input id="tags" ui-select2="{tags:tags, simple_tags: true}" multiple ng-model="myTags" style="width: 150px;">
    <p>$scope.tags = {{tags}}<p>
    </div>
</div>

Here's a gist with a full test application: https://gist.github.com/poundifdef/6544542

Am I using the select2 module improperly? Or is there a bug in the module itself?

The ng-model directive should be the $scope that will populate the select input. Use ng-model="tags"instead.

EDIT When you have 

<input id="tags" ui-select2="{tags:tags, simple_tags: true}" multiple ng-model="myTags" style="width: 150px;">

The tagsin ui-select2="{tags:tags, simple_tags: true}"refers to the model you want to appear as options in the dropdown while myTags in ng-model="myTags" refers to the options that are selected.

If you want the list to be loaded with some options selected, set them in the controller as $scope.myTags. This should normally be a sub-set of the options (that is, $scope.tags here).
