When using 'infiniteScrollContainer' attribute the calculation isn't according to the chosen container

[Michaelzvu]

The behavior of the directive when choosing another container instead of the window isn't correct.
it's happens when I set new container by 'infiniteScrollContainer' attribute or by adding 'infiniteScrollParent' attribute.

for example:

<div id="test"
         infinite-scroll="$ctrl.addInfiniteScrollItems()"
         infinite-scroll-distance="1"
         infinite-scroll-disabled='$ctrl.isAllItemsLoaded'
         infinite-scroll-container="'#test'">
        <div class="app" ng-repeat="item in $ctrl.applications">
            <something></something>
        </div>
    </div>
