Magento Admin Custom Tab in Catalog Product - magento

Question

I have created a custom tab under catalog product, the tab is coming fine but when i click on the tab the template for the block is not loading. It echo what i type but it is not fetching the template. I write this function in a class HTC_Csvpricing_Block_Adminhtml_Catalog_Product_Tab extends Mage_Adminhtml_Block_Template implements Mage_Adminhtml_Block_Widget_Tab_Interface
public function _construct()
{
parent::_construct();
echo "I m here";
$this->setTemplate('csvpricing/tab.phtml');
}
Here what I write in app/design/adminhtml/default/default/layout/csvpricing.xml
<csvpricing_adminhtml_csvpricing_index>
<reference name="content">
<block type="csvpricing/adminhtml_csvpricing" name="csvpricing" />
</reference>
</csvpricing_adminhtml_csvpricing_index>
<adminhtml_catalog_product_edit>
<reference name="product_tabs">
<action method="addTab">
<name>csvpricing_tab</name>
<block>csvpricing/adminhtml_catalog_product_tab</block>
</action>
</reference>
</adminhtml_catalog_product_edit>
Please guide what I am missing.
Thanks

You can do as follow :
Module config.xml
<config>
<adminhtml>
<layout>
<updates>
<your_module>
<file>your-module.xml</file>
</your_module>
</updates>
</layout>
</adminhtml>
</config>
Create the layout XML in /app/design/adminhtml/default/default/layout/your-module.xml:
<?xml version="1.0"?>
<layout>
<adminhtml_catalog_product_edit>
<reference name="product_tabs">
<action method="addTab">
<name>your_module_some_tab</name>
<block>your_module/adminhtml_catalog_product_tab</block>
</action>
</reference>
</adminhtml_catalog_product_edit>
</layout>
Create the tab block in {your_module}/Block/Adminhtml/Catalog/Product/Tab.php:
class Your_Module_Block_Adminhtml_Catalog_Product_Tab
extends Mage_Adminhtml_Block_Template
implements Mage_Adminhtml_Block_Widget_Tab_Interface
{
/**
* Set the template for the block
*/
public function _construct()
{
parent::_construct();
$this->setTemplate('catalog/product/tab/some-tab.phtml');
}
/**
* Retrieve the label used for the tab relating to this block
*
* #return string
*/
public function getTabLabel()
{
return $this->__('Some Tab');
}
/**
* Retrieve the title used by this tab
*
* #return string
*/
public function getTabTitle()
{
return $this->__('Some Tab');
}
/**
* Determines whether to display the tab
* Add logic here to decide whether you want the tab to display
*
* #return bool
*/
public function canShowTab()
{
return true;
}
/**
* Stops the tab being hidden
*
* #return bool
*/
public function isHidden()
{
return false;
}
}
you need to create a data helper to support translation, if your module does not have one already.
Make the tabs template in /app/design/adminhtml/default/default/template/catalog/product/tab/some-tab.phtml:
<div class="entry-edit">
<div class="entry-edit-head">
<h4>Some Heading</h4>
</div>
<div class="fieldset fieldset-wide">
<div class="hor-scroll">
<!-- your content here -->
</div>
</div>
</div>
