Add new value to JSON object

[XpertWorlock]

Let's say I have the following JSON object :

 

({"test":{"status":"good"}})

 

Now how would I add "test2" to make it :

 

({"test":{"status":"good"}, "test2":{"status":"bad"} })

 

Thanks for any help

obj.test2 = {
  status: 'bad'
}

I knew it was something simple but the ol brain wasn't thinking.
