Jquery click events not triggering after adding an element to the DOM, despite using on()
Question
I think I must be missing something obvious here.
I have a function bound to the click event on a class. The function adds an element to the DOM in a location that depends on the position of the clicked element. Basically, if you click a box in several rows of boxes, then an information display div is added under the row of the clicked box (see example code).
However, the way I've implemented this it seems that once the information display div has been added, the click event no longer triggers on any of the elements appearing in the DOM before the added div. It will still trigger on elements after the added div.
I've delegated the event handler via on(), so I'm not sure why it's not staying bound. What dunderheaded obvious thing am I missing please?
Thanks in advance for your valuable time.

The div you are adding stretches all the way from the top of the screen to it's position, covering all elements above it.
Add this css style:
#cdisplay {
float: left;
}

Fast answer, Add this to css:
#cdisplay {
z-index: -1;
}
The problem is when you append #cdisplay, it overshadows the #cboxes so you can not click on them anymore.
