Can not call script function from C++ in Troque3D Beta3

Greetings!

Introduction
below is the modifications of my source code:

file "GameTSCtrl.h"
class GameTSCtrl : public GuiTSCtrl
{
Point3F mMouse2DPos;

static void initPersistFields();
void onRightMouseDown( const GuiEvent &event);
void onRightMouseUp( const GuiEvent &event);
};

file "GameTSCtrl.cpp"

void GameTSCtrl::initPersistFields()
{
Parent::initPersistFields();
addField("mMouse2DPos", TypePoint3F, Offset(mMouse2DPos, GameTSCtrl));
}

void GameTSCtrl::onRightMouseDown( const GuiEvent &evt) {
mMouse2DPos = getRoot()->getCursorPos();
if ( isMethod("onRightMouseDown") )
{
Con::executef( this, "onRightMouseDown" );
}
Con::printf("onRightMouseDown x=%d, y=%d", mMouse2DPos.x, mMouse2DPos.y);
}

void GameTSCtrl::onRightMouseUp( const GuiEvent &evt) {
mMouse2DPos= getRoot()->getCursorPos();

if ( isMethod("onRightMouseUp") )
{
Con::executef(this, "onRightMouseUp");
}
Con::printf("onRightMouseUp x=%d, y=%d", mMouse2DPos.x, mMouse2DPos.y);
}

Script file "PlayGui.gui"
%guiContent = new GameTSCtrl(PlayGui) {
canSaveDynamicFields = "1";
profile = "GuiContentProfile";
horizSizing = "right";
vertSizing = "bottom";
position = "0 0";
extent = "640 480";
minExtent = "8 8";
visible = "1";
cameraZRot = "0";
forceFOV = "0";
noCursor = "1";
};

function PlayGui::onRightMouseDown(%this)
{
echo("Right Mouse Down");
}

function PlayGui::onRightMouseUp(%this)
{
echo("Right Mouse Up");
}


Problem Statement
The "onRightMouseDown" and "onRightMouseUp" functions are can not be called from GameTSCtrl.cpp


Any ideas?
