Call Function on when app opens

Question

I'm really new at BB10, but I need to update a HTML app for BB10 where I need to call a function when the app opens. I have no idea where to begin and I can't find anything on Google. Can anyone give me some direction?

EDIT: I found a file called app.js with a function App.init = function(){..}

Safe to assume this is where I call the function?

OK I guess I was a noob, but I just put it in the <script> tag where I declare the js file.

<script type="text/javascript" src="js/BlackBerry-Test.js">
        $(document).ready(function () {
            updateFeed(true);
        });
</script>
