How to bind yii action in extjs - yii

Question

I am working in extjs+Yii. My yii action is:
public function actionCreateNew()
{
$record=Qbquestionset::model()->findAllByAttributes(array("questionPaperId"=>1));
foreach($record as $rec)
{
if($rec==NULL)
{
echo"Paper does not exists";
}
else
{
echo $rec->questionId;
$record1=Qbquestion::model()->findByAttributes(array("questionId"=>$rec->questionId));
echo "</br>". $record1->question;
echo "</br>".CJSON::encode(array("Question"=>$record1->question));
}
}
}
This function is retrieving Questions and sending it in json format.
Now in extjs I had created model, view, controller and view as=
Model= Question.js
Ext.define('Balaee.controller.Question',
{
extend:'Ext.app.Controller',
stores:['Question'],
models:['Question','QuestionOption'],
views:['question.Question','question.QuestionView'],
init:function()
{
console.log("inside Question controller");
},
});
Store.js===
Ext.define('Balaee.store.Question', {
extend: 'Ext.data.Store',
model: 'Balaee.model.Question',
autoLoad: true,
proxy:{
type: 'ajax',
//url:'data/poll.json',
api: {
//read: 'data/question.json',
read: 'http://localhost/NewQuestion/index.php?r=QuestionBank/qbpaper/CreateNew',
},
reader: {
type: 'json',
//root: 'questions',
}
}
});
View=== questionView.js
Ext.define('Balaee.view.question.QuestionView',
{
extend:'Ext.view.View',
id:'QuestionViewId',
alias:'widget.questionView',
store:'Question',
config:
{
tpl:'<tpl for=".">'+
'<div id="main">'+
'</br>'+
'<b>Question :-</b> {Question}</br>'+
//'<p>-------------------------------------------</p>'+
//'<tpl for="options">'+ // interrogate the kids property within the data
//'<p>&nbsp&nbsp<input type="radio" name="opt" >&nbsp{option}</p>'+
//'</tpl></p>'+
'</div>'+
'</tpl>',
itemSelector:'div.main',
}
});//
So I am binding yii action to store by mentioning its url. But store is not retrieving any value. So what changes are needed to retrieve yii optputs in extjs store?

One problem I can see is with your Yii action. You should return JSON result, while you returning something weird.
Try this:
public function actionCreateNew()
{
$record = Qbquestionset::model()->findAllByAttributes(array("questionPaperId" => 1));
$result = array();
foreach($record as $rec) {
if ($rec != NULL) {
$result[] = $record1->question;
}
}
echo CJSON::encode(array(
'success' => true,
'root' => $result,
'total' => count($result)
));
}
You should also define root: 'root' property of reader.
