How to inject dependency into existing controller in AngularJS
<p>I have this controller that is defined on the body element:</p>

<pre><code>app.controller('bodyController', ['$injection1', '$injection2',
    function($injection1, $injection2){
        // doing stuff here
}]);
</code></pre>

<p>Now somewhere else, I want to be able to inject another dependency into this controller. Pseudo-code:</p>

<pre><code>app.controller('bodyController').inject(['$injection3', function($injection3){
    // doming more stuff here
});
</code></pre>

<p>Is this possible at all?</p>
