knockout.js - data-bind text default value

Question

In knockout.js I have a very standard field that looks like this:

<label data-bind="text: JobTitle"></label>

What I'd like is to have a default value specified in here if the text value is null, for example "No Job Title Specified".

Is this possible to do in knockout.js?

Thanks.

Even shorter than other code samples is the following:

ko.extenders.withDefault = function(target, defaultValue) {
    target.subscribe(function(input) {
        if(!input) target(defaultValue)
    });
    return target
};

With the initiation

ko.observable().extend({ withDefault: "some Default" })
