In addition lazy loading of root level nodes is implemented by handling pagination and sorting using page and sort events by making a remote query using the information passed to the events such as first offset, number of rows and sort field for ordering. Filtering is handled differently as filter elements are defined using templates, use the event you prefer on your form elements such as input, change, blur to make a remote call by passing the filters property to update the displayed data. Note that, - in lazy filtering, totalRecords should also be updated to align the data with the paginator.
