under ng-if

[khsmaxim]

Under ng-if vertical orientation works wrong attrs.$observe('orientation', ...
pos = 'top';
posOpp = 'bottom';
values still "left" and "right"

faster way to solve it - put watchers under timeout

 $timeout(function() {
     // listen for changes to values
     scope.$watch('min', setMinMax);
     scope.$watch('max', setMinMax);
     scope.$watch(function () {
        return modelMin();
     }, setModelMinMax);
     scope.$watch(function () {
        return modelMax();
     }, setModelMinMax);
 }, 0);
