Loading Javascript file when module load

Question

I am developing custom Module in Magento 1. Now I would like to load my module specific JS file when then module enabled. In this regard I used below xml code in a separate xml file named as module name which is placed inside layout folder. My module don't have any controller.

<default>
    <reference name="head">
        <action method="addJs">
            <js>brand_logo.js</js> 
        </action>
    </reference>
</default>

But the JS file is not loading at the time of module loading.

How can I do that??
