AngularJS, combine these two methods into one

I have a div

<div id="slideHolder" ng-mouseenter="fadeIn()" ng-mouseleave="fadeOut()">
...
</div>

And the content in the middle fades in an out on mouseenter/leave

$scope.fadeIn = function()
{
    TweenLite.to("#zoomInButton",0.3,{opacity:1});  
}

$scope.fadeOut = function()
{
    TweenLite.to("#zoomInButton",0.3,{opacity:0});  
}

Is it possible combine those two functions into one using an if statement ? I know how I'd do it in jQuery, but not sure how to in Angular. Thanks

Edit: This is how I did it in jQuery

$("#slideHolder").hover(
    function() {
        $("#zoomButton").stop(true,true).fadeIn();
    },
    function() {
        $("#zoomButton").stop(true,true).fadeOut();
    }
);

Granted they are technically two function still, I was able to shorthand them into the hover method

I was able to figure this one out

<div id="slideHolder" ng-mouseenter="fade($event)" ng-mouseleave="fade($event)">
....
</div>

and in angular

$scope.fade = function(event)
{
  (event.type == 'mouseover') ? TweenLite.to("#zoomInButton",0.3,{opacity:1}) : TweenLite.to("#zoomInButton",0.3,{opacity:0});  
}
