The one of $('#test checkbox') is never called, because you don't have an tag with name checkbox .
It's because you put the input inside the label so when you click the checkbox you also click every parents (that's called bubbling) EDIT, credit to @t. Niese : in fact there is no bubbling here because the issue is when you click on label and it only bubbles up.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
