How to remove bindings from node in knockout?

Question

I've found that in theory ko.cleanNode() should remove bindings from node if called, but in this example it doesn't seem to work.

Javascript:

// View model
var vm = {
    name: ko.observable("John")
}

// Node to be added
var node = $("<div/>",{
    id: "testing",
    'data-bind' : "text: name()"
});

// First addition to body
$("body").append(node);

// Apply bindings
ko.applyBindings(vm,$("#testing")[0]);

// Remove
ko.cleanNode($("#testing")[0]);

$("#testing").remove();

$("body").append(node);

Result: You can see in jsFiddle , that node still has attached binding (event listener).

Knockout is removing the knockout related bindings from the node, but when it does so, it does not reset the node to empty values. It just stops updating the node automatically from the viewmodel, vm.

Take out line 21 of the updated fiddle.

ko.cleanNode($("#testing")[0]);

You should see when you run it, the name is now 'imnotbinding'.
