I've used knockoutjs on a few projects now and I think I could help, but the article is down, so I don't understand the context of your question.

There are several way to structure your app, but it depends on what your app does and how structured it is. On a basic level I structure every page to have a page object to handle events and setup the view model(s).

So, for default.aspx, I might have something like:

var Page = new function(){ _this = this;

  $(function(){
    //document ready
  });

  $("#dataTable").delegate(".delete",function(){
     _this.viewModel.deleteItem(ko.dataFor(this));
  });

  this.viewModel = new function(){
    var _this = this;

    //set up view model
    this.observableVal = ko.observable("");
    
    this.deleteItem = function(){
      //delete item from VM
    };

  };

};

But then you might want to have a page with multiple view models (ie UserControls that are self contained). This gets a bit tricky, especially if you want the multiple view models to interact.

Shoot me an email if you need help.
