How to clear/remove observable bindings in Knockout.js?

Question

I\'m building functionality onto a webpage which the user can perform multiple times. Through the user\'s action, an object/model is created and applied to HTML using ko.app

For a project I'm working on, I wrote a simple ko.unapplyBindings function that accepts a jQuery node and the remove boolean. It first unbinds all jQuery events as ko.cleanNode method doesn't take care of that. I've tested for memory leaks, and it appears to work just fine.

ko.unapplyBindings = function ($node, remove) {
    // unbind events
    $node.find("*").each(function () {
        $(this).unbind();
    });

    // Remove KO subscriptions and references
    if (remove) {
        ko.removeNode($node[0]);
    } else {
        ko.cleanNode($node[0]);
    }
};
