I will bet that your bike doesn't have index shifting. You need "friction" shift levers, which is how all of us learned to shift in the old days. There are still some nice friction thumb shifters being made- search for SunRace SLM10.
Oh, heck- I already did the search:
SunRace | SLM10
my vote for thumb shifters..... there are right where you need them and at least for me on a 1x8 setup work super well
