Knockout initial binding

Question

How can I use knockout if my html is already rendered. I'd like to apply binding on checkbox: when checkbox is checked I want my textarea be enabled and vice versa.

How can I achieve this?

I don't understand

How can I use knockout if my html is already rendered

but if your question is How can i enabled a textbox according to checkbox state you can try this :

<div><input type="checkbox" data-bind="checked: isTextBoxEnabled"/>Enable textbox</div>
<div><input type="input" data-bind="enable: isTextBoxEnabled"/></div>

var ViewModel = function() {
        var self = this;
        self.isTextBoxEnabled = ko.observable(true);
    };

ko.applyBindings(new ViewModel());

You shouldnt do it, but it works.

Just add the data-bind attribute to the elements. Lists of checkboxes etc wont work though
