You are jumping to a routine, using a 'call' should do the trick...

A 'call' pushes the current program counter to the stack, and then jumps to
the label.
A 'ret' poppes the program counter from the stack, and continues running
In your program you jump without pushing the program counter, when you do a
'ret' the program pops a 'random' value from the stack and continues
executing there...
