Do not use hasOwnProperty for getting data from context

[Koc]

There are cases, when ViewModels are too complex and have inheritance. So hasOwnProperty would return wrong data (null in most cases)

                // Get the variable from the context
                if (object.hasOwnProperty(key)) {
                    value = object[key];
                } else if (object.hasOwnProperty("get"+capitalize(key))) {
                    value = object["get"+capitalize(key)];
                } else if (object.hasOwnProperty("is"+capitalize(key))) {
                    value = object["is"+capitalize(key)];
                } else {
                    value = null;
                }
// -->
                // Get the variable from the context
                if (key in object) {
                    value = object[key];
                } else if (object[("get"+capitalize(key)]) {
                    value = object["get"+capitalize(key)];
                } else if (object["is"+capitalize(key)]) {
                    value = object["is"+capitalize(key)];
                } else {
                    value = null;
                }

Good point, I hadn't considered this. I'll fix it shortly.
