How to add an remove std::functions from a std::vector [duplicate]

I have a simple C++ program below which registers some callbacks/listeners which are just std::functions. And then it removes the callbacks.

Code:

#include <iostream>
#include <functional>
#include <vector>
#include <memory>

class SomeClass {
public:
    typedef std::function<void(int)> ListenerType;
    std::vector<ListenerType> m_listeners;

    void RegisterListener(const ListenerType& listener) {
       m_listeners.push_back(listener);
    }

    void UnregisterListener(const ListenerType& listener) {
        // This does not compile. Is this the right way to remove an std::function from va ector of  std::functions?
        auto position= std::find(m_listeners.begin(), m_listeners.end(), listener);
        if (position != m_listeners.end()) {
            m_listeners.erase(position);
        }
    }
};


class SomeOtherClass : public std::enable_shared_from_this<SomeOtherClass>{
public:
    SomeOtherClass(SomeClass some_class) : m_some_class(some_class) {   
    }

    void RegisterAllListeners() {
        m_some_class.RegisterListener(std::bind(&SomeOtherClass::ListenerMethod1, shared_from_this(), std::placeholders::_1));
        m_some_class.RegisterListener(std::bind(&SomeOtherClass::ListenerMethod2, shared_from_this(), std::placeholders::_1));
    }

    void UnregisterAllListeners() {
        m_some_class.UnregisterListener(std::bind(&SomeOtherClass::ListenerMethod1, shared_from_this(), std::placeholders::_1));
        m_some_class.UnregisterListener(std::bind(&SomeOtherClass::ListenerMethod2, shared_from_this(), std::placeholders::_1));
    }

private:
    SomeClass m_some_class;
    void ListenerMethod1(int value) {
        std::cout << "The value is: " << value << std::endl;
    }

    void ListenerMethod2(int value) {
        std::cout << "The value is: " << value << std::endl;
    }
};

int main() {
   SomeClass some_class;
   SomeOtherClass some_other_class(some_class);
   some_other_class.RegisterAllListeners();
   some_other_class.UnregisterAllListeners();
}

Question:
The issue is that UnregisterListener does not compile! But, this is exacly the way used to find and remove an item from a std::vector. Isnt it? What am I doing wrong?

Overall, my question is also to check whether this is the right way to add and remove listeners in C++ using std::functions?
