The set of ids in a component is effectively fixed at startup -- this allows us to do some important optimizations for binding resolution.

For an example like the above Loader should work very well; I'm not sure how close that matches your actual use case though. Have you tried using Loader?

Since createQmlObject returns the object it has created, you could possibly also look at saving the return value in an accessible property (though in the case of bindings that would likely generate a lot of warnings until the object was actually created)

Item {
    property variant rect1
    ...
    function create() {
        rect1 = Qt.createQmlObject(...)
    }
}
