(Spirit) Semantic Actions with member functions?

I am playing around with Spirit and I seem to run into an architecture problem with semantic actions. Here's a small example.

class MyGrammar : public grammar<MyGrammar>
{
public:
        template <typename ScannerT>
        struct definition
        {
                definition(MyGrammar const& self)
                {
                        TestRule = str_p("test")[&my_action];
                }

                rule<ScannerT> const&
                        start() const { return TestRulet; };

        private:
                rule<ScannerT> TestRule;
        };
};

My major problem is related to the fact that I cannot pass any custom data to my_action function. Since my_action is a global function, it has no knowledge of MyGrammar and must rely on global variables. Ideally, I would pass self to my_action to be able to hold state. What is a general way to get around this problem? The documention mentions a way to specify member functions as semantic action actors using boost's bind facilities but I was unable to get it to work.
Thanks in advance.

P.S. Sorry for a fairly newbie question, I was unable to find the answer online or in the docs.
P.P.S. I might have accidently double posted this. Sorry about that.
