Radio buttons trouble on switching

I have issue with radio buttons. When I click on another radio button and then click previous to console falls wrong id

I noticed that the type is changing the id and obtained two types with similar id http://take.ms/bljgn

This is my jsbin http://jsbin.com/cahigu/8/

May be somebody have working example of radio buttons?

If you are using ember-cli, the Yapp team released recently ember-radio-button - npm

There is also ember-radio-buttons - npm

My example with radio works too, but I don’t understand how to change related model when I choose another by radio button. I would appreciate if you’ll say how to do it :smile:
