    <p>I would advise that you use knockout mapping to add custom functionality to your data items that you can invoke from your markup. (I have created a working <a href="http://jsbin.com/eziwog/1/edit" rel="nofollow">JSBin</a> for you ) </p> <p>Your initial data remains the same and your javascript becomes:</p> <pre><code>var DataItem = function(data) { var self = this; ko.mapping.fromJS(data, {}, self); // add custom functionality to each data item here // here an alert is added that can be called via 'selectItem' in markup self.selectItem = function(){ alert("item with id " + self.OrderId() + " clicked"); }; }; var viewModelMapping = { 'DataItems': { create: function(options) { return new DataItem(options.data); } } }; var ViewModel = function(data) { var self = this; ko.mapping.fromJS(data, viewModelMapping, self); }; var vm = new ViewModel(initialData); $(document).ready(function () { ko.applyBindings(vm); }); </code></pre> <p>And your HTML table becomes (<em>removed styling for clarity</em>):</p> <pre><code>&lt;table&gt; &lt;tbody data-bind="foreach: DataItems"&gt; &lt;tr&gt; &lt;td"&gt; &lt;input type="button" value="Select" data-bind="click: selectItem" /&gt; &lt;span data-bind="text: OrderId"&gt;&lt;/span&gt; &lt;/td&gt; &lt;td data-bind="text: ItemHtml"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>You can read more about customizing mapped objects in the <strong>Customizing object construction using “create”</strong> and <strong>Customizing object updating using “update”</strong> sections <a href="http://knockoutjs.com/documentation/plugins-mapping.html" rel="nofollow">here</a></p>

    1. CORune, Thanks for taking the time to provide such a thorough answer. With some tweaks I got this working now in my code, and I have a much better understanding how/why it works. I also like how it allowed me to clearly define my models. Seems to be a lot of different ways of using Knockout that I am still unaware of.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
