[Solved] Newbie - Events not working with squareline

Bugs
1

I am a complete newbie and I am creating my UI by using squareline.
So I have created then exported the UI.
I have fixed some issues as the color depth who caused issues, the folder libraries who wasn’t reconized, enabled the debug, …
But now I am stuck because my events doesn’t look triggered.

First of all the out of the box change screen event works in preview mode but not when I upload it on the real ESP32. When I click on my button nothing happen.
Then I have tried to implement a custom event by calling a function so I have found

void ui_event_Btn1(lv_event_t * e)
{
    LV_LOG_USER("Clicked (src)"); //I have added this line for debug
    lv_event_code_t event_code = lv_event_get_code(e);
    lv_obj_t * target = lv_event_get_target(e);
    if(event_code == LV_EVENT_CLICKED) {
        Move1Clicked(e);
    }
}

and

void Move1Clicked(lv_event_t * e)
{
	// Your code here
	LV_LOG_USER("Clicked");
	
	lv_label_set_text_fmt(ui_lblPosition, "1");
	//lv_label_set_text(ui_lblPosition, "1");
}

But again nothing happen I just see the following logs when I reset the ESP32 but nothing when I click

I have let the default ui.ino do I have to change soemthing in

/*Initialize the display*/
    static lv_disp_drv_t disp_drv;
    lv_disp_drv_init( &disp_drv );
    /*Change the following line to your display resolution*/
    disp_drv.hor_res = screenWidth;
    disp_drv.ver_res = screenHeight;
    disp_drv.flush_cb = my_disp_flush;
    disp_drv.draw_buf = &draw_buf;
    lv_disp_drv_register( &disp_drv );

    /*Initialize the (dummy) input device driver*/
    static lv_indev_drv_t indev_drv;
    lv_indev_drv_init( &indev_drv );
    indev_drv.type = LV_INDEV_TYPE_POINTER;
    indev_drv.read_cb = my_touchpad_read;
    lv_indev_drv_register( &indev_drv );

Did I forget something? How can I resolve it?

primary move this into if because squareline call func for all events

secondary show and check my_touchpad_read, seems it dont work with your lcd touch.

That was indeed the my_touchpad_read who wasn’t correc. It is very weird that the example doesn’t work there where a missing line:
void my_touchpad_read( lv_indev_drv_t * indev_driver, lv_indev_data_t * data )
{
uint16_t touchX = 0, touchY = 0;

bool touched = false;
tft.getTouch( &touchX, &touchY, 600 );
touched = touchX != 0 || touchY != 0; //This line was missing

if( !touched )
{
    data->state = LV_INDEV_STATE_REL;
}
else
{
    data->state = LV_INDEV_STATE_PR;

    //I have also added those 2 lines
    // Inverted as we have rotated the screen (pins up)
    touchX = screenWidth - touchX;
    touchY = screenHeight - touchY;

    /*Set the coordinates*/
    data->point.x = touchX;
    data->point.y = touchY;

    Serial.print( "Data x " );
    Serial.println( touchX );

    Serial.print( "Data y " );
    Serial.println( touchY );
}

}

Thank you for your support
