Dua after Taraweeh

Assalamu Alaikum.
After taraweeh prayer I recite the following dua
'Allahumma inna nasalukal jannati wa naujoobika minan nar. Ya Khalikal jannati wan nar. Berahmatika Ya Azizu, Ya Gaffaru, Ye Karimu, Ya Sattaru, Ya Rahimu, Ya Jabbaru, Ya Khalique, Ya Barr. Allahumu ajirna minan nar, Ya Mujiru, Ya Mujiru, Ya Mujir. Berahmatika Ya Arhamur Rahimeen.'
I am doing it correctly? I have learned it when I was a little kid.
