adding blueprints to scene negates previous

Ok guys the title might be a little ambiguous but basically i have an explosion _bp that is triggered when i press the left ctrl .and this works fine … however if i add another explosion bp to the scene i was expecting the pressing of left ctrl to explode both .But instead it only explodes the latest bp i placed . i would like to blow up all bombs that are placed in the scene I was assuming i could place multiple of the same object in the scene and they would all react to my key presses .This is not the case
any help guys ?

So i found the simple solution to this . I had to disable consume input in the explosion bp .
