Oops, forgot the detonator.
Bane (or someone) gives a small speech about giving people hope, and how hope is the most dangerous thing. By allowing the bomb to decay rather than just setting it off (which they promised to do if anyone tried to escape or anyone tried to rescue them or interfere with the bomb etc) it gave people hope, hope a way out will be found, hope that things will get better, etc
The negative impact of hope being something that he would be familiar with due t his time in the pit, the hope that there's a rope and a wall climb to freedom, but an almost impossible escape giving them all false hope.
Not the most sensible tactic, but it is a typical comic book evil guy compulsion type of plan
