+ // called once for each file in the selection for XHR file uplaods, else
+ // once for each file selection.
+ // The upload starts when the submit method is invoked on the data parameter.
+ // The data object contains a files property holding the added files
+ // and allows to override plugin options as well as define ajax settings.
+ // Listeners for this callback can also be bound the following way:
