You can retrieve the button1 handle after calling "main". For instance:
local button1 = dlg[1][1]
Or you can save the button as a custom dialog attribute inside "main" then
retrieve it outside. For instance:
return iup.dialog{vbox; title = title, button1 = button1}
Then
local button1 = dlg.button1
> button1 = iup.button{title = 'Botão 1'}
> iup.SetAttribute(button1, 'ACTION', 'button1_action') vbox = iup.vbox{button1}

Because it will assume that your callback is implemented in C and associated
with IupSetFunction. In Lua you must use a Lua function to directly associate
the callback.
