Javascript: Push JSON String as Value of an Input String (Escape/Unescape)

Question

Following Situation (see plunker here: http://plnkr.co/edit/fOJ5zRvqCKvOC3olik8S?p=preview ):

<input ng-model="x" type="text">
<button ng-click="add(x)"> push input's value </button>

Text-Input has a JSON-String as value (I put it manually)

{ "i":3, "j":5 }

and I want to transfer its value and push it afterwards in Controller into an array. As you can see I've an escaped version of it in the array, what I want to avoide.

How should my escape/unescape strategy look ? Where should I begin?
