javascript - How can I use contact listener in Box2D with Cocos2D-Javascript?

Question

I already implemented all the objects, their velocity, etc. but the Box2D functions are within a Cocos2D inherit function. I can't find a way to create a listener class within this. Does anyone have any idea on how to do this? I can't seem to find the solution in Google. Thanks!

Found it. I can just create a listener inside the function and override its own functions/attributes.

var listener = new b2ContactListener    
listener.BeginContact = function (contact) {
  //console.log(contact.GetFixtureA().GetBody().monster);
}
listener.EndContact = function (contact) {
  //console.log(contact.GetFixtureA().GetBody().GetUserData());
}
listener.PostSolve = function (contact, impulse) {

}
listener.PreSolve = function (contact, oldManifold) {

}
