Trigger a socketed spell when you use a skill question

I have now chosen Trigger a socketed spell when you use a skill seven times when i unveil weapons at Jun. it dosent seem to work, i was told u only have to choose Trigger a socketed spell when you use a skill three times?
im still at level 1 of the skill with 8 seconds.
Do i have to do something more before im able to raise the level of Trigger a socketed spell when you use a skill?

now i have unveiled Trigger a socketed spell 9 times but skill still lvl 1?
