Remove usage of DOM.html( view.el ) as it's not recommended usage

The correct usage is to be view.setElement( DOMselector ).  Use case: If
a view has event listeners, upon the first DOM.html, event handlers are
setup correctly. Upon subsequent DOM.html calls, the event handlers are
not mapped, as jQuery's html method calls reset, which removes all event
handlers. Using the setElement ensures event handlers are set correctly.
