My c++ eventlistener fails to compile (term does not evaluate to a function taking 1 arguments)

#include <iostream>
#include <string>
#include <queue>

using namespace std;

class ListenerTest;

class IListener {
};

template<typename ...T>
class Event {
public:
};

template<typename ...T>
class EventListener {
public:
    typedef void (ListenerTest::* memberFunc) (Event<T...> event);

    EventListener<T...>(memberFunc f) : f(f) {
    }
    void trigger(Event<T...> event) {
        f(event); // - - - - ERROR - - - -
    }
private:
    memberFunc f;
};

template<typename ...T>
class EventHandler {
public:
    EventHandler<T...>() {
    }
    void addListener(EventListener<T...>& listener) {
        this->listeners.push_back(listener);
    }
    void removeListener(EventListener<T...>& listener) {
        this->listeners.erase(std::remove(this->listeners.begin(), this->listeners.end(), listener), this->listeners.end());
    }
    void fire(Event<T...>& event) {
        for (EventListener<T...> listener : this->listeners) {
            listener.trigger(event);
        }
    }
private:
    vector<EventListener<T...>> listeners;
};

class ListenerTest : IListener {
public:
    void triggerTest(Event<int, int> event) {
        cout << "triggerTest" << endl;
    }
};



int main() {
    auto pia = &ListenerTest::triggerTest;

    ListenerTest lTest;

    Event<int, int> myEvent;
    EventHandler<int, int> handlerTest;
    EventListener<int, int> listenerTest(pia);

    handlerTest.addListener(listenerTest);
    handlerTest.fire(myEvent);
}
