Problem with DevExpress Treelist

My problem is that my treelist does not do anything after I expand the nodes. This is my view

@{
    ViewBag.Title = "EstructuraFinanciera";
}
@if (Session["username"] != null)
{
  <text>
    Bienvenido @Session["username"].ToString()
  </text>
  <script>
    $('#myModal').modal('hide');
  </script>
<br />


}
else
{
    Response.Redirect(Url.Action("Login", "Inicio"));
}

<br />
<hr />



@Html.Action("_TreeListPartial")

My partial view created by the devexpress wizard

@{
                    var treeList = Html.DevExpress().TreeList(settings => {
                        settings.Name = "TreeList";
                        settings.CallbackRouteValues = new { Controller =

 settings.SettingsEditing.AddNewNodeRouteValues = new { Controller =

                        settings.SettingsEditing.UpdateNodeRouteValues = new

                        settings.SettingsEditing.DeleteNodeRouteValues = new

                        settings.CommandColumn.Visible = true;

                        );

                        settings.SettingsPager.Visible = true;
                        settings.SettingsSelection.Enabled = true;
                    });
                        if (ViewData["EditError"] != null){

 treeList.SetEditErrorText((string)ViewData["EditError"]);
                    }
 }   
 @treeList.Bind(Model).GetHtml()

And then my deployed nodes, there does not happen

I do not know what it could be. Thank you in advance to who can help me.
