Yii gridview CHTML :: dropdown as value不起作用

Question

I'am trying to implement a dropdownlist inside the gridview, but it is not working.

Here's my code

$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'user-grid',
'dataProvider'=>$model->roadies_search(),
'filter' =>$model,
'columns'=>array(

    array(
        'name'=>'hname_search',
        'header'=>'Hospital Name',
        'value'=>'($data->AssociatedHospitals) ? $data->AssociatedHospitals : ""',
    ),
    array(
        'type'=>'raw',
        'header'=>'Users',
        'id' => 'test',
        'value'=>function(){
                $res=Yii::app()->db->createCommand("SELECT name,id FROM med_user WHERE rank>3")->queryAll();
                $html = '<select name="user" style="width:100%;">
                <option selected>Select User</option>
                ';
                foreach ($res as $key) {
                    $html.='<option value="'.$key['id'].'">'.$key['name'].'</option>
                    ';
                }
                $html.='</select>';
                return $html;
            },
        ),
)

));

I have tried it using the following function too:

public function getUsername(){
    $res=Yii::app()->db->createCommand("SELECT name,id FROM med_user WHERE rank>3")->queryAll();
    return CHtml::dropDownList('usersselectlist'.$this->id,'user_id',CHtml::listData($res, 'id', 'name'));
}

I want to show all the users as a dropdown, for every row in the gridview.

EDIT

I figured out that the dropdown works fine for firefox, but the problem is with chrome. It is not showing the selected values.

Here's an example

        'header'=>'Users',
        'id' => 'test',
        'value'=>function(){
                // but better prepare data in model and set here from controller
                $dataReader = Yii::app()
                    ->db
                    ->createCommand("SELECT name,id FROM med_user WHERE rank>3")
                    ->query();
                $dropList = array();
                foreach ($dataReader as $row) {
                    $id = $row['id'];
                    $dropList[$id] = $row['name'];
                }
                return CHtml::dropDownList('my', null/* or selected id */, $dropList);
            },
        ),
