Using context property in Javascript. How?

bogong

Hello all!
I got stacked in very simple issue. Totally forgotten how to call from JavaScript.
Here the example *.cpp

ObjectType* oObject = new ObjectType();
oRootContext->setContextProperty("ObjectType",oObject);

in *.qml:

Component.onCompleted: {
	ObjectType.someMethod();
}

in *.js:

ObjectType.someMethod(); // this not working in JavaScript directly

What am I missing? How to make this method be working in JS directly?

someMethod must be a slot, or be annotated with Q_INVOKABLE macro. is it the case ?

What do you mean by "this not working". Do you see any error ? Nothing happens?
edit: add code

class ObjectType : public QObject {
// Like this
public slots:
    void someMethod();
// Or
public:
    Q_INVOKABLE void someInvokableMethod();
}
