[SOLVED]Qt Creator determined existing property as "non-existent property"

[rogerloh4.0]

Tried to add a new button on the MainForm.ui.qml
with already 2 are existed.
However, when I try to give commands to the 3rd button in main.qml, it gives me this message:

Cannot assign to non-existent property "button 3"

Noted: I have not change or alter any of its original property, only changed the text from "Button 3" to "Start"
