Using JavaScript To Change the HTML Contained In An External Script

I have an element on my website that is hosted externally and referenced in a script on my page.

I want to automatically change the text within this content so that it always displays tomorrow's date.

Script for the widget:

<script src="//my.externalwidget.com/12345.js" type="text/javascript" charset="utf-8" async="async"></script>

HTML contained in external script:

<div id="changeHeaderOne">THIS SHOULD DISPLAY TOMORROW'S DATE</div>

My JS:

<script type="text/javascript">
var currentDate = new Date(new Date().getTime() + 24 * 60 * 60 * 1000);
var dateParse = currentDate.toString();
var dayAbbr = dateParse.substr(0, 3);
var day = currentDate.getDate();
var month = currentDate.getMonth() + 1;
var year = currentDate.getFullYear();
document.getElementById("changeHeaderTwo").innerHTML = "Tomorrow's date is " + dayAbbr + " " + month + "/" + day + "/" + year;
document.getElementById("changeHeaderOne").innerHTML = "Tomorrow's date is " + dayAbbr + " " + month + "/" + day + "/" + year;

I know my script is working because it runs properly on #changeHeaderTwo (located in DOM) but not on #changeHeaderOne (externally hosted and loaded using the script on top).

Any ideas how to make this apply to the externally loaded code as well?

You are using document.getElementByClass() (which should really by document.getElementsByClassName()) when your div has an id. Use document.getElementById() instead.
