JS file configured in web resources not available for a velocity template rendered on confluence

[abhaykumar.rajguru]

We have a velocity template which we are calling on the click of a Custom banner button on confluence page.

We are able to render the velocity template with whatever UI we designed, however the JScript which we have defined in plugin.xml as a web resource, is not getting loaded and hence not getting applied to the velocity template. 

Any idea here?
