Yes it does produce bubbles but not all pools will exhibit the bubbles going back to the pool. It all depends on the amount of power the cell is receiving, the flow rate, and the number of return jets you have. Most pools have equalized returns and variable return jet orafices, which will distribute the bubbles more evenly throughout the pool and makes the bubbles less evident.
Why your Jandy is not working? Activating the cell then crack the union after the cell and take a water sample from there. Test the water sample for chlorine, which should indicate a higher level than what's in the pool.
Your salt level is good. Do you show any warning lights on the Jandy? What are the rest of your water chemistry results? Low stabilizer, high pH, high Phosphates, previous bromine use, or short run times will all contribute to low or no chlorine detectible in your pool.
How does your water look? If it's clear and you have not added any chlorine, it's working. Perhaps your chlorine is too HIGH and may be bleaching your test results?

Just some thoughts....
