Auto-select the new node

Hi, exists a method to select a node?

I created a button to insert nodes to tree and I want to select the new node automatically. 

// Render the TreeView by mapping its fields property with data source properties  let treeObj: TreeView = new TreeView({      fields: { dataSource: (dataSource as any).defaultData, id: 'id', text: 'name', child: 'subChild', selected: 'isSelected' }  });  treeObj.appendTo('#tree');    document.getElementById("btn").onclick = (): void => {      let node = [          { "id": "02-01-01", "name": "My photo.png", "isSelected": true }];      treeObj.addNodes(node, "01-01", null, false); //adding the node to parent node with id 01-01  }

Hi, I tried but it didn't work and I have more questions:

1. How can I use the method addNodes to insert a node in tree root? The documentation says:
 "If target node is not specified, then the nodes are added as children of the given parentID or in the root level of TreeView."

var treeObject = new ej.navigations.TreeView({ fields: { dataSource: scope.infData, id: 'id', text: 'text', child: 'child', iconCss: 'icon', selected: 'isSelected' }, ...);

treeObj.addNodes(node, null,null, false); 

I tried the above code, but the tree don't shows my new node, I had to refresh the tree. But when I use the same method to insert a child node, specifying the parent Id, it works (auto refresh the tree).

This method don't select my new node using parent Id or not.

2. Have I turn off the last selected node flag (isSelected) to works?
I printed the sourceData and all nodes have the attribute isSelected = true.

//selected attribute mapping field and newly added node data's selected field values should be same      let treeObj: TreeView = new TreeView({          fields: { dataSource: (dataSource as any).defaultData , id: 'id', text: 'name', child: 'subChild', selected: 'isSelected' }      });      let node = [          { "id": "02-01-01", "name": "Root Node", "isSelected": true }];      treeObj.addNodes(node, null, null, false); //adding the node to Root Level

Thanks a lot!

The problem was because I was trying to insert nodes passing only the node object instead of an array of nodes.
