how to bing checkboxes in ember with a list

I have a model where I have a list of all countries as below -

[{"code":"US", "name":"USA"}]

selected counties will be pass on as a list like below -

["US", "CA"]

my template has a list of checkboxes like below -

     
     
       
        <label class="checkbox-inline"></label>
    

the code above doesn't work as intended and I am trying to figure out how to configure the checkbox to achieve what I need. Any ideas?
