I already solved it, I was Initializing in Activity_Create, so I moved it to the click event of the button.

Sub Listar_Click
    Builder.Initialize("Dialog")
    Builder.Title("Months and Days")
    Builder.Items(Array As String("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"))
    Builder.ItemsCallback
    Builder.PositiveText("OK")
    Builder.Show
End Sub
