How to add new data below existing data in treetable.

On a particular event, I want to append some data at the bottom of my existing treetable. How can I do that? I was using parse but it just appends data in existing tree and not below it.

If you are using unique IDs new items will be added below the existing ones.

@nlmm01: you can specify {parent: <id>, value: } to load data as a child of a given element - http://webix.com/snippet/d4cbd5c3
