Adding a line of code to HTML5 output init() function

I have a need to add a couple of lines of code to the end of the init() function...used by my engine. Currently I have to manually add it every time I re-publish my content. Is there a way to have it automatically add it every time I re-publish?

function init() {

canvas = document.getElementById("canvas");

anim_container = document.getElementById("animation_container");

dom_overlay_container = document.getElementById("dom_overlay_container");

var comp=AdobeAn.getComposition("9249BD2A01D4914B9F884593FD1C9237");

var lib=comp.getLibrary();

var loader = new createjs.LoadQueue(false);

loader.addEventListener("fileload", function(evt){handleFileLoad(evt,comp)});

loader.addEventListener("complete", function(evt){handleComplete(evt,comp)});

var lib=comp.getLibrary();

loader.loadManifest(lib.properties.manifest);

    // ADDED CODE

    window.parent.nextType = "timer";

    window.parent.iframe_loaded();

}
