Yii 1.1.14

I'm trying to make a popup to select a year and then get some reporting output for the selected year :

The popup is generated by CJuiDialog. Inside CJuiDialog', I have a form. In the first time I had a normal submit button on the form and it worked fine. But it did not close the popup. Then I found this post : Yii - CJuiDialog Close on submit button click The button of the dialog to submit the form closes the dialog but seems not to post to the indicated url. I also tried ajaxSubmitButton() directly in the form. Same result when I click on this button. There are no JS errors, nothing in the application log.

This is my View :

    beginWidget('zii.widgets.jui.CJuiDialog',array(
            'id'=>'mydialog',
            'options'=>array(
                'title'=>'select year test',
                'autoOpen'=>false,
                'modal'=>true,
                'buttons' => array(
                    'Dialog Submit Button'=>'js:function(){
                        $.post(
                            $("#select-year-form").attr("action"),
                            $("#select-year-form").serialize(),
                            function(){$("#mydialog").dialog("close");}                     
                        );
                    }',             
                        array('text'=>Yii::t('app','reporting.select.close'),'click'=> 'js:function(){$(this).dialog("close");}'),
                ),
            ),
        ));
    ?>
    

        'select-year-form')); ?>
        

            

            
array($lastyear=>array('selected'=>true)) )); ?>
            
        
        

        'function(){$("#mydialog").dialog("close");}'),
                array('name' => 'run', 'class' => 'btn btn-success')
        ); ?>
        
    

    endWidget('zii.widgets.jui.CJuiDialog');
        echo CHtml::link(Yii::t('app','app.menu.reporting.planning.xlsabsence'), '#', array(
            'onclick'=>'$("#mydialog").dialog("open"); return false;',
        ));
    ?>

EDIT : Here's the requestheader for the ajax submit button :

For the other button its the same request header. There appears no error - so why can't I see the page r=site/about ? (actually r=site/about is just a test page, I will have to do the target page when I have resolved this problem).
