Instantiating GameObjects in Custom Game Engine

So,i'm having a bit of an issue with instantiating my gameobjects into to universe(My Scene object).

I can create an empty object from scratch and populate it from there with ease,my problem starts when i try to clone the gameobject which i just created.

My steps are

1. I create an empty gameobject (GAMEOBJECT A)
2. I add an component to it (COMPONENT A)
3. Now i create a gameobject B from A
4. GameObject B created,and the component A is in the component list of the gameobject B
5. I try to get the component using inheritance but nullptr returns

It seems when i try to clone components,it returns only the base class pointer.There i try to recreate the derived class and add it to new gameobject's component list but obviously i fail.

• If i cant solve this with inheritance how can i solve it ?
• is there better way to implement such a desing ?
• or i just fail to use inheritance in c++.If it's, can you guys point out what am i doing wrong here

This is my GameObject AKA RGameElement

class RGameElement
{
protected:
    vector<RElementComponent*> Elements;
public:
    template <class T>
    T* GetComponent() {

        int elementSize = Elements.size();

        for (int i = 0;i < elementSize;i++)
        {
            T* pr = dynamic_cast<T*>(Elements[i]);
            if (pr != nullptr)
                return pr;
        }
        return nullptr;
    }
    template <class T>
    T* AddComponent() {

        T* newElementComp = new T();
        Elements.push_back(newElementComp);
        return newElementComp;
    }
    void AddComponent(RElementComponent* targetComponent)
    {
        RElementComponent* newElement = new RElementComponent();

        *newElement = *targetElement;

        Elements.push_back(newElement);
    }

    /*void AddComponent(RElementComponent* targetComponent);*/
    vector<RElementComponent*> GetComponent() const;
}

This is my Component AKA RElementComponent

class RGameElement;

class RElementComponent
{
public:
    RGameElement* RootGameElement;
    virtual RElementComponent GetReference() { return RElementComponent(); };
    virtual void Setup() {};
    virtual void StartLogic() {};
    virtual void UpdateLogic() {};


}

and this my Instantiate via gameobject ref function

RGameElement* RUniverse::Instantiate(RGameElement* targetGameElement)
{
    RGameElement* newElement = new RGameElement();

    vector<RElementComponent*> components = targetGameElement->GetComponents();
    int componentSize = components.size();

    for (int i = 0;i < componentSize;i++)
    {
        newElement->AddComponent(components[i]);
    }

    Elements.push_back(newElement);
    return newElement;
}
