My main doubt is how to deal with the event listener, i have the following code to create the button:
boton widget.newButton{
        id = “btn001”,
        left = 370,
        top = 170,
        label = “Aceptar”,
        width = 100, height = 50,
        cornerRadius = 0,
        onEvent = irAMenu
    }
when I dont need it anymore i just call boton:removeSelf() and boton = nil ???
What happens with onEvent event?? Wouldnt it become a memory leak? Thanks in advance
