Why javascript bind doesn't work

It does work, talk.bind(p) returns the bound function:

talk.bind(p)();

Nothing is wrong with bind()-- it's just not being used correctly. bind() returns a new function which is bound to the object specified. You still need to execute that function:

function talk(){ 
        console.log(this.name + " dice: ");
}

var Person = function(name, surname){
    this.name = name;
    this.surname = surname;
}

var p = new Person("Mark", "Red");

var markTalks = talk.bind(p);

markTalks();    // logs properly

There is nothing wrong with bind, it returns a function which is bound to the object passed as argument. So you need to invoke it like this

talk.bind(p)();
