knockout.js - バインディングの問題でノックアウト

Question

ノックアウト「ウィズ」バインディングで困っています。バインドできます。ネストされたオブジェクトは問題なくバインドできますが、ネストされたモデルはバインドできません。私はそれをすべて間違っていますか、それとも「with」バインディングの範囲外ですか。

var viewModel = function(){
    var self = this;

    self.anObject = {
        test: ko.observable("I'm and object bound by WITH.")   
    }

    var aFunction = function (){
        var self = this;
        self.test = ko.observable("I would like to be bound by WITH");   
    }

};
ko.applyBindings(new viewModel());

var viewModel = function(){
    var self = this;

    self.anObject = {
        test: ko.observable("I'm and object bound by WITH.")   
    }

    self.aFunction =ko.computed(function (){
        var self = this;
        self.test = ko.observable("I would like to be bound by WITH");
        return self.test;
    })
};
ko.applyBindings(new viewModel());

var viewModel = function(){
    var self = this;

    self.anObject = {
        test: ko.observable("I'm and object bound by WITH.")   
    }

    var ViewModel2 = function (){
        var self = this;
        self.test = ko.observable("I would like to be bound by WITH");   
    };

    self.aFunction = new ViewModel2();

};
ko.applyBindings(new viewModel());
