v1.0.8 two instance of same directives(or controller) in one scene

[soonwait]

I had add two directives to one view same time. like this:

<div ui-view>
  <div test-my-directive data-ng-if="model1">DIV 1<div>
  <div test-my-directive data-ng-if="model2">DIV 2<div>
<div>

I used $css.bind(....., $scope) in controller of directive

when i try to close DIV2 by set model2 === false
DIV1'css style dispeared unexpectly!!! why ????

It's a Suggestion as:
every call of $css.bind(..., $scope) for same stylesheet url should save all the refrence of $scope
while $scope.$on('$destroy' before to $css.remove, shuld check if refrence is 0, only 0 can be remove, otherwise JUST 'remove' the refrence of $scope.

I have try to fix this

line 459
