Store new values into JSON - angularjs

Question

I have a $http.post that gives me a JSON
$http.post(url, {headers: {'Content-Type': 'application/json'} })
.success(function (data) {
myService.initialize(data);
})
The service in which I store the JSON looks like this:
app.service('myService', function() {
var json = "";
this.initialize = function(data) {
json = data;
};
});
This is the JSON I get:
{
"values": {
"id": "ABC_123",
"infotypes": [
{
"infotype": "AA1234",
"syften": [
{
"syfteId": 0
}
]
},
{
"infotype": "BB4567",
"syften": [
{
"syfteId": 0
}
]
}
]
}
}
Now, my problem is that I want to add a new infotype "CC6789" with syfteId "0" into the JSON.
I know how to access the different parts in the JSON, to display them in tables using ng-repeat and so on. But I don't have a clue how to add something into it.

If you wanna just do it in-memory, you can add a method to your service that can add some kind of infotype object:
app.service('myService', function() {
var json = "";
this.initialize = function(data) {
json = data;
};
this.addInfoType = function(infoType) {
if(json !== '') {
json.infotypes.push(infoType);
} else {
throw new Error('no json');
}
}
});
// somewhere else
myService.addInfoType({
"infotype": "CC6789",
"syften": [
{
"syfteId": 0
}
]
});
Keep in mind, this doesn't do any validation to the data structure you're passing into the service, so you might want to add that.
