Can anyone find the script error?

Not sure how you managed to copy and paste and ruin the syntax of the callback. The original issue was that the callback syntax was incorrect and that the callback function name didn't match. And now it's the same issue, along with the fact that you converted a boolean into a string.

Damn, I didn't saw that. It's true: Jump and jump.

How I couldn't see that?
