yii add more textbox not saved in database - php

Question

In my view the form as
<table width="90%" border="0" cellspacing="2" cellpadding="2" id="table-data" align="center" style="border:1px dashed #CCCCCC" class="table table-vcenter table-striped">
<tr class="tr_clone">
<td> % Completion</td>
<td> <?php echo $form->textField($model_result,'floatPaymentpercentage[]',array('class'=>'form-control','placeholder'=>'%')); ?></td>
<td> <?php echo $form->textField($model_result,'varAmount[]',array('class'=>'form-control','placeholder'=>'Amount')); ?></td>
<td><input type="button" name="add" value="Add" class="tr_clone_add btn btn-xs btn-warning"></td>
</tr>
Here i have two textboxes for payment terms..if i save ones it will be saved.
If i add more the last will not saved in database
In my controller we can use print_r()
echo ("<pre>"); print_r($_POST); echo ("</pre>");exit;
The default text field values only shown here.
Here the text fields are added dynamically.
The dynamic added text field's values are not displayed.
In my model the rules are
public function rules()
{
return array(
array('floatPaymentpercentage','required'),
array('varAmount','required'),
);
}
here is the java script for add more
<script type="text/javascript">
$(document).on('click','.delete',function(){
$(this).closest('tr').remove();
});
$("input.tr_clone_add").live('click', function() {
if($(this).val() == "Add")
{
var $tr = $(this).closest('.tr_clone');
var $clone = $tr.clone();
$clone.find(':text').val('');
$tr.find('.tr_clone_add').val('Delete')// set value to Delet
$tr.find('.tr_clone_add').val('Delete')// set value to Delet
.toggleClass('tr_clone_add delete')// toggle classes
.unbind('click'); // unbind the current events from button
$tr.after($clone);
}
else
{
$(this).closest('tr').remove();
}
});
</script>
Please help me to fix this.
Here i can add js for funuction add more
Thanks
