Touchgfx, set text problem.

[ABURM]

Hi Guys.

I want to set textarea. I created the new texts.

And program is here;
Model.cpp

void Model::tick()
{
    static uint32_t counter = 0;
    const uint32_t updateInterval = 5;
    touchgfx::TypedTextId Bat4TextId;
    counter++;
    if (counter >= updateInterval)
    {
        switch (BAT4_CAN_Rx.fields.BAT4_State)
        {
            case CHARGE_MODE: Bat4TextId = T_CHARGE; break;
            case RELAXING_MODE: Bat4TextId = T_RELAXING; break;
            case DISCHARGE_MODE: Bat4TextId = T_DISCHARGE; break;
            case READY: Bat4TextId = T_READY; break;
            case COMPLETE: Bat4TextId = T_COMPLETE; break;
            default: Bat4TextId = T_UNKNOWN; break;
        }
		counter = 0;
    }
	if (modelListener)
	{
		modelListener->updateStatusData(Bat4TextId);
	}
}

ModelListener.hpp

class ModelListener
{
public:
    ModelListener() : model(0) {}
    
    virtual ~ModelListener() {}

    void bind(Model* m)
    {
        model = m;
    }

    virtual void updateStatusData(touchgfx::TypedTextId bat4TextId){}
protected:
    Model* model;
};

screenPresenter.cpp

void screenPresenter::updateStatusData(touchgfx::TypedTextId bat4TextId)
{
	view.updateStatusText4(bat4TextId);
}

screenPresenter.hpp

class screenPresenter : public touchgfx::Presenter, public ModelListener
{
public:
    screenPresenter(screenView& v);

    /**
     * The activate function is called automatically when this screen is "switched in"
     * (ie. made active). Initialization logic can be placed here.
     */
    virtual void activate();

    /**
     * The deactivate function is called automatically when this screen is "switched out"
     * (ie. made inactive). Teardown functionality can be placed here.
     */
    virtual void deactivate();

    virtual ~screenPresenter() {}

    virtual void updateStatusData(touchgfx::TypedTextId bat4TextId) override;
private:
    screenPresenter();

    screenView& view;
};

screenView.hpp

class screenView : public screenViewBase
{
public:
    screenView();
    virtual ~screenView() {}
    virtual void setupScreen();
    virtual void tearDownScreen();

    virtual void updateStatusText4(touchgfx::TypedTextId bat4TextId);
protected:
};

screenView.cpp

void screenView::updateStatusText4(touchgfx::TypedTextId bat4TextId)
{
	Unicode::snprintf(BT4_Status_Value_TextBuffer, BT4_STATUS_VALUE_TEXT_SIZE, "%s", touchgfx::TypedText(bat4TextId).getText());
	BT4_Status_Value_Text.invalidate();
}

BT4_Status_Value_Text buffer is 25 byte. When I compile the program it doesn't give any errors. But when I load, program is doesn't work.TFT screen and other hardwares (canbus, status led etc.) is not working. If I assign any text id directly to "bat4TextId" the program runs and I see the text I assigned on the screen.

void screenView::updateStatusText4(touchgfx::TypedTextId bat4TextId)
{
	bat4TextId = T_CHARGE;
	Unicode::snprintf(BT4_Status_Value_TextBuffer, BT4_STATUS_VALUE_TEXT_SIZE, "%s", touchgfx::TypedText(bat4TextId).getText());
	BT4_Status_Value_Text.invalidate();
}

All text ids are defined in TextKeysAndLanguages.hpp.

I think I can't link the Bat4TextId with the bat4TextId in presenter. What's the problem?
