As i said, its a layer issue only. Content within list(row) cannot be accessed directly, its overlapped with one more layer and checkbox and other fields will not have access. So if you clicked on the list, it will take you to next screen.
Increase your z-index css property within a input checkbox tab,
<input type="checkbox" name="checkboxlist" style="z-index:999999999" ......
Try this. higher z-index values brings the field to front for better accessing. If possible i will share the sample code later.
