Problem with injection #28

Halo, I am a newbie in mach_inject and facing a problem that cannot fix during my coding, so I decide to ask here.

Current I am trying to inject a bundle to Finder, it all works well and in Activity Monitor I can see my bundle reside in there.

However the code inside my bundle does not execute.

I would like to ask how do I kick start the execution of my code in the bundle?

Currently in the bundle I only have a void load() function and inside it print a line to indicate it has loaded to console.

Is it the right way to kick start?

Thanks!
