Detect a button click in the browser_action form of a Google Chrome Extension

How can something so simple be so impossible?

All I want to do is click the browser_action button of my extension, open a form with a couple of settings, and then click the button on the form to kick off a process.

I cannot for the life of me get the button click in the background form to work.

I have tried to get the example at http://developer.chrome.com/extensions/contentSecurityPolicy.html#H2-3 to work, but it doesn't. Is there a difference between rules for browser_action and background? Is that why my event listener is not firing?

Can someone provide a working example, please?

manifest.json:

{
    "name": "Convert",
    "version": "0.1",
    "description": "Converts the current page",
    "browser_action": {
        "default_icon": "exticon.png",
        "default_popup": "background.html"
    },
    "content_scripts": [{
        "matches": ["*://*/*"],
        "js": ["contentscript_static.js"]
    }],
    "permissions": [
        "tabs", "http://*/*", "https://*/*"
    ]
}

        if (null == localStorage["htmlImport"])
           localStorage["htmlImport"] = false;

        // Called when the user clicks on the browser action icon.
        chrome.browserAction.onClicked.addListener(function(tab) {
            console.log('in listener');
                 // execute the content script
