yii update clistview by dropdownlist - yii

Question

I'm a very newbie in Yii framework. I would like to create a page. Which is when the dropdown list change, the listview/gridview will be change by dropdown value.
this is my view
<div class="row">
<?php
$records = Company::model()->findAll();
$company_list = CHtml::listData($records, 'id', 'name');
echo CHtml::dropDownList('company_id','', $company_list,
array(
'onchange'=>"$.fn.yiiListView.update('ajaxListView', {url: '".Yii::app()->createUrl('department/dynamicsectionlist')."?company_id='+$('#company_id option:selected').val()})",
'prompt'=>'Please select a company',
)); ?>
</div>
<?php
$this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
'itemView'=>'_view_section',
'id'=>'ajaxListView',
));
?>
This is model
public function search()
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('id',$this->id);
$criteria->compare('name',$this->name,true);
$criteria->compare('p_id',$this->p_id);
$criteria->compare('created',$this->created,true);
$criteria->compare('updated',$this->updated,true);
$criteria->compare('company_id',$this->company_id);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
This is Controller
public function actionDynamicsectionlist()
{
$company_id = $_POST['company_id'];
$criteria=new CDbCriteria();
$criteria->condition .= 't.id IN (SELECT t2.id, t2.name FROM department t2 WHERE t2.company_id = :company_id)';
$criteria->params[':company_id'] = $company_id;
$dataProvider = new CActiveDataProvider( 'Department', array( 'criteria' => $criteria, ) );
$this->render( 'sectionlist', array( 'dataProvider' => $dataProvider ) );
}
But it is not working. Please help me.

I solved it.
This is controller
// Initial view (department/depatmentlist)
public function actionDepartmentlist()
{
$model=new Department('search');
$model->unsetAttributes(); // clear any default values
$model->p_id = 0;
// $dataProvider->getData() will return a list of Post objects
// $dataProvider=new CActiveDataProvider('Department');
$this->render('list_department',array(
'model'=>$model,
));
}
// when the user selected the company from dropdown list
public function actionDynamicsectionlist()
{
$model=new Department('dsearch');
$model->unsetAttributes(); // clear any default values
$model->p_id = 0;
if(isset($_GET['company_id']))
$model->company_id = $_GET['company_id'];
$this->render('sectionlist',array(
'model'=>$model,
));
}
This is model (nothing change)
public function search()
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('id',$this->id);
$criteria->compare('name',$this->name,true);
$criteria->compare('p_id',$this->p_id);
$criteria->compare('created',$this->created,true);
$criteria->compare('updated',$this->updated,true);
$criteria->compare('company_id',$this->company_id);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
This is view (list_department.php)
<h1>Departments List</h1>
<div class="row">
Company<br />
<?php
$records = Company::model()->findAll();
$company_list = CHtml::listData($records, 'id', 'name');
echo CHtml::dropDownList('company_id','', $company_list,
array('prompt'=>'Please select a company',)); ?>
</div>
<?php
/*
for ListView
$this->widget('zii.widgets.CListView', array(
//'dataProvider'=>$dataProvider,
'dataProvider'=>$model->search(),
'itemView'=>'_view_section',
'id'=>'ajaxListView',
));
*/
?>
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'department-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'name',
//'p_id',
'created',
'updated',
//'company_id',
),
));
?>
<?php
Yii::app()->clientScript->registerScript('search',
"$('#company_id').change(function(){
var companyId = $('#company_id option:selected').val();
$.fn.yiiGridView.update(
'department-grid',
{ type: 'GET',
url: 'http://localhost/mmaig_ceo/ceo-control-system/index.php?r=department/dynamicdepartmentlist&ajax=department-grid&company_id=' + companyId
}
);
});
")
?>
