Default Technical question - reverse depth charges

So something I've been wondering is - why didn't, and don't, the subs do the same thing, only in reverse? When you hear the destroyer coming, release depth charges filled with explosives. These reverse depth charges would be light enough to rise rapidly and explode once near or at the surface, deterring, damaging or even sinking the DD. Sounds to me like a great anti-anti-ASW measure. In fact, it sound to me like they'd be ten times as effective as depth charges, as DDs often had to make educated guesses as to where the sub was, while the sub knows that once it's detected, the DD will past right overhead.

So given that it would probably work so well if it worked, and that
it's such a simple concept, there has to be a good reason why "reverse depth charges", or "surface charges", aren't in widespread use. Anyone care to educate me?
