Modifying the property of an array inside of an array and have it show up on the UI?

Please see the JS fiddle here: http://jsfiddle.net/zWjaD/6/
How come the update to the name property is not being reflected on the UI?

Hello,

 Because you are not updating the right property. The original code is 

this.ranks[0].set("name", name);    

However the items of the ranks array don't have a "name" property. They have "id" and "person". You need to use 
this.ranks[0].set("person.name", name);    

Here is the updated fiddle: http://jsfiddle.net/zWjaD/9/
