How to sort timetable object in ember.js

1

Hi guys, i got this object from backend API. Thing is when i edit timetable it sends this way and response is kind a same as it is. So for mobile app it shows timetable start from sunday. What i want is week starts from Monday. How can i do it in ember way.

"timetable": {
        "sun": {
            "open": 480,
            "close": 1320
        },
        "sat": {
            "close": 120,
            "open": 600
        },
        "fri": {
            "close": 120,
            "open": 480
        },
        "thu": {
            "close": 120,
            "open": 480
        },
        "wed": {
            "open": 480,
            "close": 120
        },
        "tue": {
            "close": 0,
            "open": 480
        },
        "mon": {
            "close": 0,
            "open": 480
        }

So now i have to sort this object as Mon, Tue, Wed, Thu, Fri, Sat, Sun
