    <p>I am using MVC 4.0 with knockout.js to create a page that will call to a database every 5-10 seconds, and update the model with the new object retrieved from the database, then update the view with the new model. </p> <p>Currently I am making the initial JSON get call and this is returning the model, and I am then able to bind this to the view. I then set up the getJSON call again to do the update every 10 seconds, and it will execute the function and get back the data, but no update is seen on the screen. I have tried calling the ko.applyBindings after each call, but there is still no update on the page, then it crashes the browser after a few calls.</p> <p>I'm not sure what exactly I'm doing wrong. I have included the relevant parts of the code below.</p> <p>JavaScript:</p> <pre><code>&lt;script type="text/javascript"&gt; var viewModel; var update = setInterval(function () { $.getJSON( "/Home/Get", {}, function (model) { viewModel = model; bindViewModel(viewModel); }); }, 10000); $(document).ready( function () { $.getJSON( "/Home/Get", {}, function (model) { viewModel = model; bindViewModel(viewModel); }); }); function bindViewModel(viewModel) { ko.applyBindings(viewModel); } &lt;/script&gt; </code></pre> <p>Table to Display Model </p> <pre><code>&lt;div data-bind="foreach: { data: Events, as: 'evnts' }"&gt; &lt;span data-bind="text: evnts.LastUpdate"&gt;&lt;/span&gt; &lt;table id="EventsTable" style="display:inline; float:left;"&gt; &lt;tbody&gt; &lt;tr id="EvntsHeader" data-bind="visible: evnts.IsVisible"&gt; &lt;td&gt; &lt;span data-bind="text: evnts.Name"&gt;&lt;/span&gt; &lt;/td&gt; &lt;tr&gt; &lt;td&gt; &lt;table id="MarketsTable"&gt; &lt;tbody data-bind="foreach: { data: evnts.Markets, as: 'markets' }"&gt; &lt;tr&gt; &lt;td id="MarketHeader"&gt; &lt;span data-bind="text: markets.Name"&gt;&lt;/span&gt; &lt;span data-bind="text: markets.NumberOfRunners"&gt;&lt;/span&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;table id="SelectionTable"&gt; &lt;tbody data-bind="foreach: { data: markets.Selections, as: 'selections' }"&gt; &lt;tr id="Selections"&gt; &lt;td&gt;&lt;span data-bind="text: selections.Number, visible: selections.IsVisible"&gt;&lt;/span&gt;&lt;/td&gt; &lt;td&gt;&lt;span data-bind="text: selections.Name, visible: selections.IsVisible"&gt;&lt;/span&gt;&lt;/td&gt; &lt;td&gt;&lt;span data-bind="text: selections.CurrentPrice, visible: selections.IsVisible"&gt;&lt;/span&gt;&lt;/td&gt; &lt;td&gt;&lt;span data-bind="text: selections.OpeningPrice, visible: selections.IsVisible"&gt;&lt;/span&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p></p> <p>Controlller - JSON Get</p> <pre><code>[AcceptVerbs(HttpVerbs.Get)] public JsonResult Get() { var model = new TestModel {LastUpdate = DateTime.Now}; if (TestConstants.Update == false) { GetModelFirstTime(model); TestConstants.Update = true; } else { UpdateModel(model, DateTime.Now); } return Json(model, JsonRequestBehavior.AllowGet); } </code></pre>

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).
