Image is not taking border-radius css attribute on android

[OPADA-Eng]

What I did:
<IC:WebImage id="my-image-1" stretch="fill" class="user img-circle" placeholder="~/loading.gif" width="150" height="150" src="{{ Image(photo) }}"> </IC:WebImage>

and in app.css :
.user.img-circle{ border-radius: 100; width:150; height: 150; margin-bottom: 10; }
