[jQuery] Cannot trigger mouseout for function bound by hover.

[Gerlando]

I'm using hover to bind methods to a DOM object. Triggering the
mouseover event works as expected, but when using mouseout/mouseleave
nothing happens. What am I doing wrong?

newRollHandler  = new rollHandler(this);
$(this).hover(newRollHandler.over,newRollHandler.off);
$(this).trigger("mouseover");
$(this).trigger("mouseout");
