We automatically close issues that contain the default title test as spammers often leave the title unchanged (or add a bit of spammy text to it).

It's hard to follow what's going on because your code is missing semicolons, so it has broken syntax. Could you please fix the code and provide an easily reproducible example we can run in one click?
