Quantity is not updating in magento site - database

Question

we have marketplace multi vendor/seller site. we gave an option for seller to update the product information through frontend.....
As it is marketplace site, we have many sellers.
seller A uploaded product A in frontend [quantity = 20 ]
if seller B have same product , he will assign the same product to his account [quantity = 5 ]
in backend it showing 20 + 5 = 25 quantity.
now the problem is when seller A update the quantity from 20 to 40, it showing 40 in frontend and once we refresh the page, it showing only 35. Means after refreshing it showing quantity of [ Seller A qty- Seller B qty ]
but it should show seller A Quantity.
Before It was working properly , later we did some code changes than we are facing this Problem.
before the qty textfield was looking like as in image :
once we click on "edit " button present in image, it looks like below image :
But we decided to display below image :
so we changed code to look like above image. Than this problem happened.
Before Code : [Everything was working fine ]

Present code
In the above code, we comment some lines and we replaced some codes as below.
commented code
<!-- <img onclick="showField('<?php echo $products->getId(); ?>'); return false;" src="<?php echo $this->getSkinUrl('marketplace/images/icon-edit.png'); ?> -->
**script**
//$wk_jq(qtyId).toggle()
//$wk_jq(updateButton).show();
//hideReset(product_id);
//jQuery(updatedqty).show().delay(2000).fadeOut();
Replaced code 1 )

I found solution for 1st problem.
public function massupdatesellerproAction(){
if($this->getRequest()->isPost()){
if(!$this->_validateFormKey()){
$this->_redirect('marketplace/marketplaceaccount/myproductslist/');
}
$ids= $this->getRequest()->getParam('product_mass_update');
$price= $this->getRequest()->getParam('price');
$special= $this->getRequest()->getParam('specialprice');
$i=1;
foreach ($ids as $key => $value) {
$i=$i+1;
$qty = $this->getRequest()->getParam('stock'.$i);
$product = Mage::getModel('catalog/product')->load($value);
$product->setPrice($price[$key]);
$product->setSpecialPrice($special[$key]);
//$product->setQty($qty);
$product->save();
$stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($value);
$stockItem->setData('manage_stock', 1);
$stockItem->setData('qty', $qty);
$stockItem->save();
}
Mage::getSingleton('core/session')->addSuccess( Mage::helper('marketplace')->__('Products has been sucessfully deleted from your account'));
$this->_redirect('marketplace/marketplaceaccount/myproductslist/');
}}
