Comply with WCAG 2.0 H44 - label form control association

Applying what is said in
http://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/H44
This important for visually impaired people as well as for
people who prefer clicking labels instead of inputs (like me).

Doing some clean up:
* Consistent representation of objects
* Creating elements in jQuery does not require closing tags,
  if no attributes are specified.
* Removal of unused variable in constructor.
