Some misunderstand in AngularJS

In my controller I have this definition:

var self = this;
this.game= gameArchive;

I have this row in my view:

<input type="checkbox"
    checklist-model="builderStep2.game.ModelItems"
    checklist-value="model.Id"> {{model.Name}}

where builderStep2 is controller name.

And also I have this row code:

self.game.ModelItems.push(someID);

When user press on the check button the array is created and the value is added to game.ModelItems, but when I try to fill the array programmatically by this row: 

self.game.ModelItems.push(someID);

it seems that array is not creates and I get this error:

TypeError: Cannot read property 'push' of null

Any idea why does it happen?

push() belongs to Array.prototype. If game.ModelItems is not an array, push() will not work.

I'm not sure what gameArchive is doing, but you could try in your controller this.game.ModelItems = []; and I have a feeling push() would work.
