This is a common problem,sometimes lasting up-to 10-15 years.
What you need to do is change some routine,i.e,keep a gap of atleast 2-3 hours between dinner and bedtime,give no liquids before bed.
Children usually pass urine in bed at a fixed time after sleep,you'll have to time it and wake him up just before that time to go to the toilet.
All these steps help in diminishing the problem.
Give it some time with patience,he'll be fine.
