RemoteMove to fire the event on a node of a TreePanel the following error occurs:

"The control with ID 'treeReport' not found"

Basically I created a TabPanel dynamically with a button that creates dynamically by clicking a tab which is another type TreePanel and this tree has an event RemoteMove that moving a node tree is triggered the event.

I created a basic example to reproduce the problem:

Code:
<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">

    protected override void OnInit(EventArgs e)
    {
        TabPanel tabMaster = new TabPanel
        {
            ID = "tabMaster",
            Width = 400,
            Height = 200
        };
        this.Form.Controls.Add(tabMaster);

        Ext.Net.Panel pnlStart = new Ext.Net.Panel
        {
            ID = "pnlStart",
            Title = "Start"
        };
        tabMaster.Items.Add(pnlStart);

        Ext.Net.Button btnCreate = new Ext.Net.Button
        {
            ID = "btnCreate",
            Text = "Create"
        };
        btnCreate.DirectClick += btnCreate_DirectClick;
        pnlStart.Items.Add(btnCreate);
    }

    protected void btnCreate_DirectClick(object sender, DirectEventArgs e)
    {
        TreePanel treeReport = new TreePanel
        {
            ID = "treeReport",
            Title = "Reports",
            EnableDD = true,
            Mode = TreePanelMode.Remote
        };

        Ext.Net.TreeNode nodeRoot = new Ext.Net.TreeNode
        {
            NodeID = "nodeRoot",
            Text = "Root"
        };
        treeReport.Root.Add(nodeRoot);

        Ext.Net.TreeNode node1 = new Ext.Net.TreeNode
        {
            NodeID = "node1",
            Text = "Node 1"
        };
        nodeRoot.Nodes.Add(node1);

        Ext.Net.TreeNode node2 = new Ext.Net.TreeNode
        {
            NodeID = "node2",
            Text = "Node 2"
        };
        nodeRoot.Nodes.Add(node2);

        treeReport.RemoteMove += treeRelatorio_RemoteMove;
        treeReport.Render("tabMaster", RenderMode.AddTo);

        var tab = X.GetCmp<TabPanel>("tabMaster");
        tab.SetActiveTab("treeReport");
    }

    protected void treeRelatorio_RemoteMove(object sender, RemoteMoveEventArgs e)
    {
        if (e.NodeID.Equals("node1") && e.TargetNodeID.Equals("node2"))
            e.Accept = true;
        else
            e.Accept = false;
    }
