Aloha Editor and Ember

I'm having difficulties integrating the Aloha Editor http://ift.tt/1FD9D9W to Ember.

I'm able to generate an editable area. However, I cannot make the editable text Bold.

I created this JSBin: http://ift.tt/15SKgWh

This line of code aloha.ui.command(aloha.ui.commands.bold); is compiled with no error in my app but my text do not become bold. I'm using an example straight out of Aloha getting started guide: http://ift.tt/15WgPnc. See step 2 to get explanation for the button that bold the text.

I'm thinking that I should implement the step 2 in another way to make it work with Ember. I don't now how however.

Thanks for your guidance.
