Adding a tooltip to an input box

Question

I am using the CSS.Tooltips library to try an get a tooltip to show up on an input tag. I can get it to work on a p tag but not an input tag. Any ideas?

Here is link to the fiddle: http://jsfiddle.net/cwlanca/BumU5/1/

html

<p data-tip="This is the text of the tooltip">This is a paragraph of text that has a tooltip.</p>
</br>
</br>
</br>
<input data-tip="This is the text of the tooltip" value="44"/>

Css

[data-tip] {
    position:relative;

}
[data-tip]:before {
    content:'';
    /* hides the tooltip when not hovered */
    display:none;
    content:'';
    display:none;
    border-left: 5px solid transparent;
    border-right: 5px solid transparent;
    border-bottom: 5px solid #1a1a1a;
    position:absolute;
    top:30px;
    left:35px;
    z-index:8;
    font-size:0;
    line-height:0;
    width:0;
    height:0;
    position:absolute;
    top:30px;
    left:35px;
    z-index:8;
    font-size:0;
    line-height:0;
    width:0;
    height:0;
}
[data-tip]:after {
    display:none;
    content:attr(data-tip);
    position:absolute;
    top:35px;
    left:0px;
    padding:5px 8px;
    background:#1a1a1a;
    color:#fff;
    z-index:9;
    font-size: 0.75em;
    height:18px;
    line-height:18px;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
    border-radius: 3px;
    white-space:nowrap;
    word-wrap:normal;
}
[data-tip]:hover:before,
[data-tip]:hover:after {
    display:block;
}
