CKEditor toolbar is disabled when displayed in a modal window

I am trying to integrate CKEditor on my website and I have installed the files at the root level of my MVC4 application. I have a page with a modal window on it where I wish to display a template which the user can edit to create their email. The modal window is called using jquery reveal-modal.
