Customize a select with font-awesome - css

Question

This is what I have actually:
HTML
<label class="select">
<select name="email" id="email">
<option>aaaa</option>
<option>aaaa</option>
<option>aaaa</option>
<option>aaaa</option>
<option>aaaa</option>
<option>aaaa</option>
</select>
</label>
CSS
.cforms select {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
.select {
position:relative;
display: -moz-inline-stack;
display: inline-block;
vertical-align: middle;
zoom: 1;
*display: inline;
margin-top:40px;
}
.select:after {
content: "\f0dc";
font-family: FontAwesome;
color: #000;
padding:8px;
position:relative;
right:35px;
top:0px;
background:red;
z-index:-1;
width:10%;
line-height:10%;
}
Problem
Actually, no arrows appears near my select.
Could you please help me with this.
I searched on the web for examples, but I can't make it works.
Thanks.
