A problem in easing

[Vahid-Designer]

Hello all. I have a container as below:

 

.section-fixed{
position:fixed;
width:0px;
height:0px;
top:-280px;
right:-280px;
overflow:hidden;
-webkit-border-radius:50%;
-moz-border-radius:50%;
border-radius:50%;
background:transparent;
opacity:0;
z-index:10;
}

which there is a few items within it:

.item-f{
text-decoration:none;
top:calc(50% - 15px);
left:calc(50% - 15px);
position:absolute;
border-radius:50%;
width:30px;
height:30px;
text-align:center;
color:black;
font-size:25px;
cursor:pointer;
}

<section class="section-fixed">
<div class="main-menu-f">
<div id="HomeButton" class="item-f">A</div>

I wrote a code with TweenLite as below:

if(//some condition){
TweenLite.to('.item-f:nth-child(1)', 0.6, {x:0.98 * -220.56290407832017,y:0.98 * 30.932307155207802,rotation:360,autoAlpha:1,ease:Back.easeOut.config(1.87)});
else{
TweenLite.to(".item-f:nth-child(1)", 0.6, {x:0,y:0,rotation:-360,autoAlpha:0,ease:Back.easeIn});
}

The problem is for when if condition is true, unfortunately ease function doesn't work correctly and the element moves in its way, simply. But when the else condition is true, Back.easeIn done correctly. What's going on? Can everybody help me at this?
