JQueryUI dialog as bindable template in KnockoutJS - jquery-ui

Question

This question is exposing that one: integrating jquery ui dialog with knockoutjs
I have Model with array of items like this:
var viewModel = {
items: ko.observableArray([])
}
viewModel.items.push(new DialogModel("title 1"));
viewModel.items.push(new DialogModel("title 2"));
viewModel.items.push(new DialogModel("title 3"));
Next I show these items in markup using foreach statement
<div data-bind="foreach: items">
<div data-bind="text: title"></div>
<button data-bind="click: open">Open</button>
<button data-bind="click: close" >Close</button>
</div>
I need to show JQueryUI dialog on clicking buttons and this dialog should be binded to ItemModel instance.
I do not want to include dialog code inside loop because it is copying in result DOM and makes it huge. I'd like to use dialog in template for example.
JSFiddle mockup here http://jsfiddle.net/YmQTW/8/
Any thoughts?

You can create an array that contains only the opened dialogs and bind this array to the template.
With this code only dom of opened dialogs are duplicated.
var DialogModel = function (title) {
var self = this;
self.title = ko.observable(title);
self.isOpen = ko.observable(false);
self.open = function () {
viewModel.shownDialogs.push(self);
setTimeout(function () { self.isOpen(true); }, 0);
};
self.close = function () {
this.isOpen(false);
};
self.isOpen.subscribe(function () {
if(self.isOpen() === false)
viewModel.shownDialogs.remove(self);
})
};
var viewModel = {
items: ko.observableArray([]),
shownDialogs: ko.observableArray([]),
};
The view :
<div data-bind="foreach: shownDialogs">
<div data-bind="template : 'tmpl'"></div>
</div>
See fiddle
I hope it helps.
