Adding extra values in json object

For Example

I have Object named tempobj and below are tempobj[0] and tempobj[1] sample data.

I want to add extra info like name and status this object

tempobj ["info"]["name"] = "title";
tempobj ["info"]["id"] = "23243";

But when i do stringify , Jquery is ignoring this value...how can i add data like this to this kind of structure.

 [
        [{
            "name": "Breakfast",
            "value": "buffalo strip ",
            "check": 0
        }, {
            "name": "snack ",
            "value": "pecan pie butter",
            "check": 0
        }, {
            "name": "dessert",
            "value": "chocolate zucchani brownie",
            "check": 0
        }],
        [{
            "name": "Breakfast",
            "value": "Stir Fried Kale and Baccon  ",
            "check": 1
        }, {
            "name": "snack ",
            "value": "Smoked Salmon nori roll  "
        }, {
            "name": "dessert",
            "value": "Apple muffins"
        }]
