You need to look at the html of the select after it is updated. make sure that the name of the select is the same before and after your dynamic update.
You said that on edit it doesn't set the proper values on the select. which select are you talking about, the state select, or are you talking about the cities select after you choose a state? what is the name of the partial that you created?
