Using jstree v3, you can associate attributes using the plugin like so:-

// create instance
var inst = $("#tree-id").jstree();
// create node definition
var node = {
    id: "new_node_id",
    text: "New Node",
    li_attr: { "data-files": "false" },
    a_attr: { "data-url": "some_url" }
};
// create node
var newNodeId = inst.create_node("#", node);

The expected format of the node parameter (from the source comments):

// Expected format of the node (there are no required fields)
//{
//  id: "string" // will be autogenerated if omitted
//  text: "string" // node text
//  icon: "string" // string for custom
//  state: {
//      opened: boolean  // is the node open
//      disabled: boolean  // is the node disabled
//      selected: boolean  // is the node selected
//  },
//  children: []  // array of strings or objects
//  li_attr: { }  // attributes for the generated LI node
//  a_attr: { }  // attributes for the generated A node
//}

and the expected format of the create_node parameters:

// create_node(par, node, pos, callback, is_loaded)

// par (object) - the parent node (to create a root node use "#" (string) or `null`)
// node (object) - the data for new node (valid JSON object, or a simple string with the name)
// pos (object) - index to insert the node, "first" and "last" are supported, default is "last"
// callback (function) - a function to be called once the node is created
// is_loaded (boolean) - internal argument indicating if the parent node was succesfully loaded

// returns (string) - the ID of the newly create node
