You are "paying" for the extra attention, not for answers. You got the attention, which was exactly what you paid for.
I would also advise you to consider the possibility that there are problems with your question that make it harder for people to answer it. Consider taking some time to go over the question (generally several times, if it's important enough for you to bounty) looking for things that might be unclear, lacking in detail, or just not as well written out, or look for information that appears to be overly wordy and not helpful that can be trimmed down. By improving on the question itself (whether it's bountied or not) can help you get better answers. In particular pay attention to any comments that would indicate confusing or unclear points in the question that you can consider addressing in edits.
FYI, the above was written without looking at the bounty question. After looking at the question, it reaffirmed my suspicion that the question is not of good quality, and that is likely contributing to the lack of answers.
Some red flags in your question are the use of "doesn't work". What does "doesn't work" mean? What, specifically, does it do, and what should it do instead. You linked to a related post, but didn't indicate what problems you had using the answer in that question. Was there a problem with it, was the question itself different (if so, how, and what impact does that difference have). More detail about what you did try would also help. After describing the specific problems with your solution, you should probably actually post that solution rather than just saying you wrote one (although try to ensure you include only what's relevant, don't dump a lot of unrelated code).
