It is absolutely impossible for us to guess, which line causes the disaapearence of the button. But you can set some breakpoints in your code and step through the program line by line. Then you can locate the line and post it here, if you have further questions.

Are you familiar with the debugger?
Set a breakpoint in the first line of the program. Then run the program line by line until the button disappears. Then the current line causes the troubles.
As far as I can see, the code you've posted does neither create nor delete a button.
