Include link in form label?

I'm looking to include a link in a form label as such:

<%= form.check_box 'eula' %>
<%= form.label 'eula', "I agree to the <a href='#' id='eula-link'>EULA</a>", class: 'label-checkbox' %>

Rails writes the HTML out, as it probably should, but how would I accomplish this? Clicking EULA opens a JS popup. I was thinking of embedding a link_to in there somehow ?
