You can’t just declare a party. You have to start by having friends, and then they invite their friends, and then they invite their friends…
I’m sure it’s not what you actually mean or think, but the way you are talking here you come across as entitled to the time and attention from everyone in your town. I could summarize this post as you saying “I did something nice for other people, so now they are required to like me.” People don’t work that way.
Anyways you seem very motivated to grow your community and I wish you the best of luck. There is a lot of good feedback in this thread.
