Object not updating after localstorage get

In the following I try to test whether an object has been stored in localstorage, and if not to fill it with initial variables.

var TimerData = $localstorage.getObject("TimerData", "{}");

if(!TimerData.hasOwnProperty("timerState")) {
   TimerData["timerState"]             = "run";
   TimerData["timeOutMode"]            = false;
   TimerData["timeOutStartDate"]       = null;
   console.log("test line", TimerData)
};

However, running the console at line "test line" returns {} despite that I filled TimerData with variables lines before.

$localstorage.getObject looks as follows:

getObject: function(key, fallBack) {
      return JSON.parse($window.localStorage[key] || fallBack);
},

My guess is that the operation is dealing with async problems (taking data from localstorage takes longer).

How can this be overcome?

It looks like you are setting the value of "TimerData" to an empty object.

I think you can simplify this using standard js notation (you definitely dont need a special $localstorage adapter because you are using ionic). Ionic should respect standard js notation (although purely speculation on my part) 

            var TimerData = localStorage.get("TimerData");

            if (!TimerData.timerState) {
                TimerData["timerState"] = "run";
                TimerData["timeOutMode"] = false;
                TimerData["timeOutStartDate"] = null;
                console.log("test line", TimerData)
            }

Jakee1 has the right idea but but you asked about angular... Instead of

var TimerData = $localstorage.getObject("TimerData", "{}");

I would create local storage first, then assign a var to it.

$localStorage.$default({TimerData: {}});
var TimerData = $localStorage.TimerData;

This will only setup localStorage to {} if it doesn't exist ety
