Dhaka skipper Nasir Hossain continued his good run with the ball, finishing with 2-19 in three overs.
Earlier, Dhaka put Comilla under pressure early on. Pacer Al-Amin Hossain bowled a wicket maiden as Comilla were reduced to 9-1 after four overs.
But Comilla recovered from the early slump thanks to Charles and Khushdil. Jaker then hit a four and a six in the final over against Taskin Ahmed to end the Comilla innings on a high.
Earlier, Dhaka won the toss and asked Comilla to take first strike.
