var test = {
    name: "foo",
    sayHello: function(){
        console.log("my name: " + this.name);
    }
};


test.sayHello(); // -> my name: foo

var eineKopie = test.sayHello;

eineKopie(); // -> my name: 



// so ruft jquery die callbacks auf
var someCallback = function( sagHallo ){
    sagHallo();
};


someCallback(test.sayHello); // my name: 

someCallback($.proxy(test.sayHello, test)); // my name: foo
