I am attempting to obtain the text value of the newly created node AFTER the user edits the name of the new node and presses Enter.
When I do this:
The event you might be looking for is rename_node.jstree. It would look like:
rename_node.jstree
.on('rename_node.jstree', function (e, data) { //data.text is the new name: alert(data.text); });
