Observable using jquery

jquery.observe.js

var observe = function (obj) {
  var pojo = jQuery({});

  jQuery.each({ 'on': 0, 'one': 0, 'off': 0, 'trigger': 'emit' }, function (method, alias) {
    obj[alias ? alias : method] = function () {
      pojo[method].apply(obj, arguments);
      return obj;
    }
  });

  return obj;
};

You would use it like so:

var method = function () {
  var self = this;

  observe(self);

  self.on('event', function () {
    ...
  });
};
