How to transform a regular JavaScript object to ObservableObject?

[fbaptiste]

The kendo documentation specifies two ways to create an observable object: 

var viewModel1 = new kendo.data.ObservableObject( {
  field1: "value1",
  field2: "value2"
});

var viewModel2 = kendo.observable( {
 field1: "value1",
  field2: "value2"
});

but what should be used when a regular javascript object already exists, and needs to become observable?
for example, a DTO object that is being returned by a web service or one that is already created as follows:

var viewModel = {
    name: "John Doe"
};

Hi Fred,

Something like this should work - 

var viewModel = { name: "John Doe" };

viewModel = kendo.observable(viewModel);
