CMS embed button interaction not working in IE

I’m having trouble with a popup interaction not triggering in Internet Explorer (works everywhere else as far as I’ve seen).

Here’s the page where you should see a button (“Let’s See It”) that opens a popup form to fill out: Introduction to the Harvard Four-Drive Model

I use CMS for the blog pages and this one in particular has an embed code for the button. Here’s the code used there:
<div class="centered"><a href="#" class="button" data-ix="paul-herr-form-popup-blog-3"><span class="text-span-3">LET'S SEE IT</span></a></div>

This should trigger the popup modal interaction on click, which it does in other browsers, but not in IE. I can’t find this particular issue anywhere else. Does anyone know a workaround for this?

Thanks for your help!
Jason
