jQuery.Controller.prototype.update  function     

Called if an controller's jQuery helper is called on an element that already has a controller instance of the same type. Extends this.options with the options passed in. If you overwrite this, you might want to call this._super.

Examples

$.Controller.extend("Thing",{
init: function( el, options ) {
   alert('init')
},
update: function( options ) {
   this._super(options);
   alert('update')
}
});
$('#myel').thing(); // alerts init
$('#myel').thing(); // alerts update
