Replace resetTooltip with bootstrap's fixTitle

* resetTooltip totally destroyed and regenerated the
  tooltip while fixTitle simply replaces the text in
  the existing element.

* resetTooltip also called an asyncronous function
  with no suitable callback resulting in a messy
  setTimout workaround. fixTitle is syncronous.
