mock orange does not bloom
My 3 mock orange shrubs bloomed the first year I planted them, and have not bloomed - or budded the past 4 years. In year 2 pruned back to 3 inches. They have grown well, tall, but no flower buds. They are in a berm with southeast exposure. Late afternoon sun is filtered through birch clump leaves.

http://www.gardeningknowhow.com/ornamental/shrubs/mock-orange/mock-orange-bushes.htm I believe the flower buds were pruned off. Do not prune this year and wait to prune until the shrub blooms. Then prune to the desired shape without taking off more than 1/3rd of the shrub. Also prune immediately after it blooms to avoid cutting off the flower buds. Mock Orange also do best if they have moist but not wet soil. Many shrubs also need to recover from transplantation and pruning before they have the energy to bloom. I think patience and care is all that is needed.
