I'm looking for unbind functionality in knockout. Unfortunately googling and looking through questions asked here didn't give me any useful information on the topic.

I will provide an example to illustrate what kind of functionality is required.

Lets say i have a form with several inputs. Also i have a view model binded to this form. For some reason as a reaction on user action i need to unbind my view model from the form, i.e. since the action is done i want all my observables to stop reacting on changes of corresponding values and vise versa - any changes done to observables shouldn't affect values of inputs.

What is the best way to achieve this?

You can use ko.cleanNode to remove the bindings. You can apply this to specific DOM elements or higher level DOM containers (eg. the entire form).

See http://jsfiddle.net/KRyXR/157/ for an example.
