How can you remove or add JS to the theme based on criteria?

Question

I tried adding the code to template/page/html/head.phtml

if (Mage::helper('mobiledetect')->isMobile()){
  $this->addItem('js', 'js/mobile_jsscript.js');
  $this->getLayout()->getBlock('head')->removeItem('js', 'js/normal_js_script.js');
}

Is this the correct way to add and remove js based on criteria?

removeItem() function,is working when we have add js file using addItem()

through xml code :

<action method="addItem"><type>skin_js</type><name>js/normal_js_script.js</name></action>

or php code:

$this->getLayout()->getBlock('head')->addItem('skin_js', 'js/normal_js_script.js');

Or,it may be issue with params issue in function removeItem($type,$filepath)

skin_js instead of js

$this->getLayout()->getBlock('head')->removeItem('skin_js', 'js/normal_js_script.js');

Remove Item from HEAD entity

Just like:

<action method="removeItem"><type>skin_js</type><name>js/ie6.js</name></action>
