Computed data properties on prototype, using constructor

Change name

HTML:

<!-- data-linking-->

<input data-link="fullName()" />
...
<td data-link="fullName(true)" ></td>

<!-- data-bound tag-->

{^{:fullName(true)}}

Script:

//====================== Data ======================
// Constructor
var Person = function(first, last) {
        this._firstName = first;
        this.lastName = last;
    },

    // Prototype
    personProto = {
        // Computed firstName
        firstName: function() { ... },
        // Computed fullName
        fullName: fullName
    };

    //Setter for firstName - for two-way binding
    personProto.firstName.set = function(val) { ... }

    Person.prototype = personProto,

    person = new Person("Jeff", "Friedman");

// Parameterized computed observable
function fullName(reversed) {
    return reversed ? this.lastName + " " + this.firstName ...
}

// Declare dependencies
fullName.depends = ["firstName", "lastName"];

// For two-way binding of computed observables, provide a setter
fullName.set = function(val) {
    $.observable(this).setProperty({
        lastName: ...,
        firstName: ...
    });
