My advice would be: Be patient. Don't give up, and don't try to rush things...
Your baby has to get to know you and vice-versa. Breastfeeding is a very intimate relationship with a little person. There has to be trust, mutual confidence, love... It takes a little time to establish. At nine month your baby is well aware of his surroundings, his whole life just changed - and yours too!
It took me 3 months to go from bottle feeding to exclusive breastfeeding with our boy. At the beginning I had to switch from the pacifier to the breast when he was almost asleep, later on he got so used to breastfeed he would even refuse his bottle!
Good luck!
