How can get autosuggest in CakePHP

I have entered my code in my Controller like below

function keyup(){
    $this->Note->simple();
    if(strlen($searchq)>0){
        while ($row = mysql_fetch_array($getRecord)) {
     开发者_StackOverflow中文版       <a href="#"> echo $row['name']; <small> echo $row['department'];</small></a>
        } 
        return $row;
    }
}

As soon as I entered this one, it doesn't display any info.

What corrections do I require?
