Define a view model;
var mappedViewmodel = ko.mapping.fromJS({
name: 'Shahzad Khan',
age: 55
});
ko.applyBindings(mappedViewmodel, document.getElementById("simpleData"));
Display on page;
<div class="col-sm-6">
<h3 class="text-left">Knockout fromJS simple example</h3>
<div id="simpleData">
<p>name: <label data-bind="text: name" /></p>
<p>age: <label data-bind="text: age" /></p>
</div>
</div>
