Some widgets take parameters and/or options, and you can control their operation by calling the widget and passing a parameter.

Given no parameter (as shown above), the widget is created on the element (initialized). This is done for you, automatically, as long as you include the widget's associated -data attribute in the HTML. For example, a listview is initialize automatically if you include a data-role="listview" attribute.

If, for some reason, you want to initialize the widget yourself, you could leave off the data-role="listview", and then initialize a listview on the element in your own code.
