How to overload template functions

I am trying to overload template functions in a class but with no success.

How can i overLoad template in my code.

class CommandInterfaceFont
{
private:
    std::map < std::string, FontParam > lookUpMap;

public:
    CommandInterfaceFont();
    friend class SumCommandInterface;

    template <typename plug , typename typeValue >
    void SetValue(plug* geom, std::string stdstrParamName, typeValue value);

};

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

template <typename plug >
void CommandInterfaceFont::SetValue(plug* geom, std::string stdstrParamName, std::string value)
{       
            geom->setText(value);       
}

template <typename plug >
void CommandInterfaceFont::SetValue(plug* geom, std::string stdstrParamName, bool value)
{   
            geom->setUseShadow(value);      
}
