There is a bug when click outside

[yuzhigang]

the page slide can't be closed when I click outside once. I have to click twice.

       function onBodyClick(e) {
            var target = e.touches && e.touches[0] || e.target;
            if (
              isOpen &&
              body.contains(target) &&
              !slider.contains(target)
            ) {
              isOpen = false;
              scope.psOpen = false;
              scope.$apply();
            }

when function onBodyClick() is called, isOpen is false, so the page slide can‘t be closed.
so, in function psOpen(), we need to insert code after scope.psOpen = true;
isOpen = true;
I change it, it works.
