Node.js call functions within a function as callback

So, I'd like to have the following construct:

var _class = function() {};

_class.prototype.checkThis = function(callback) {
    console.log('this');
};

_class.prototype.checkThat = function(callback){
    console.log('that');
};

_class.prototype.validate = function(callback){
    var self = this;
    this.checkThis(function(err) {
        if(!err) self.checkThat(callback);
    });
}

var inst = new _class;

inst.validate();

Unfortunately, "this" does not point to the "class" within the callback of "checkThis" such that "checkThat" is unknown. Any ideas?

Is `class` a function? It should be, because otherwise `.prototype` does not work. – Bergi Mar 18 '14 at 20:27
`class` is a reserved keyword. Please use a different identifier. – Bergi Mar 18 '14 at 20:27
no, thats why "class" :D – user3434845 Mar 18 '14 at 20:28
You know you're missing curlybraces as well as using reserved keywords, as pointed out by Bergi? Here -> http://jsfiddle.net/k5wYX/1/ – adeneo Mar 18 '14 at 20:35
