a model was a simple interface that just defned a method to read an object and another one to write it: public interface IModel { public Object getObject(); public void setObject(final following basic operations: ● Generate a page unique id for the DOM element of a component. ● Write a callback for an event triggered on the page or on a specifc component (with AJAX behaviors). ● Execute JavaScript code as response to a specifc event. For the frst three operations we won’t write a single line of JavaScript! Handle AJAX events ● Now we can “ajaxify” components adding AJAX
