How do I replace the dustbin release button spring

I found that the dustbin would not lock into place because the latch would not engage. After taking it apart I found a tiny spring loose inside the latch. There is an obvious hook on the lever to release and engage latch for the dust bin, and beneath it is a well that the spring seems to slot into. However I'm not sure how to lock the other end of the spring into the well. Help would be appreciated!
