emberjs form submission in modal window

Looking over this example: http://ift.tt/19raPTu

Everything works fine to open/close the modal, but form submission does not work.

For example, take the modified jsbin example: http://ift.tt/1BiNBY2

I have an action on submit in the form tag, yet clicking Submit does not submit the form. In other words, it doesn't seem to be recognizing the action on the form tag. Any ideas?
