How do I clear cached angularjs files

I have an angularjs based web application with some functionality deployed to users that I need to hide. I've added the code to hide it and successfully verified the controls are hidden when appropriate but there are still users who have the old version of the file and can perform the undesired activities. Is there a way I can control from the server the view file to refresh on the client? (The tester was able to clear their cache but it's a burden to the users in the field)

Thanks! Scott

One way to handle this would be to version the files. For example, the following line in your index.html 

<script src="abc.js" />

could be rewritten as 

<script src="abc.js?v1" />

v1 is the current file version and should be changed for each deployment of your application when abc.js has changed.

Since index.html(the initial page) is obtained from the server, updations to abc.js will now be reflected on all your clients.

This would need to be automated in a huge application. You could use Grunt for this. You can refer the following answer on StackOverflow for automating this:

UPDATE
HTML views/templates are cached using $templateCache in AngularJS. Basically, when you request templates for the first time, browser requests the template from the server and puts it in the template cache. Any subsequent requests to the same template are served from the template cache.

If you do not want these to be cached, you could listen to the $routeChangeStart event inside app.run block to remove the specific templates. 

app.run(function($rootScope, $templateCache) {
    $rootScope.$on('$routeChangeStart', function(event, next, current) {
        if (typeof(current) !== 'undefined'){
            $templateCache.remove(current.templateUrl);
        }
    });
});
