Overriding bind and unbind

The following diagrams outline when the bind_ and unbind_ methods are called. Firstly let’s take a look at how binding works.

The unbind_ function is very similar. Upon detaching of the widget from the DOM the unbind_ method is called enabling us to perform tasks such as adding and removing listeners to avoid memory leaks. The diagram below demonstrates this.

Now that we have had a brief introduction of bind_ and unbind_ let’s see the methods put into action when we bind appropriate listeners for events.
