chrome.browserAction.onClicked.addListener not working as it should

Question

I am trying to get chrome.browserAction.onClicked.addListener working , but my app button just does not click, and no console output.

manifest.json

{
    "manifest_version":2,
    "version":"1.0",

    "name":"STFU",
    "description":"Mutes Tabs Which are not required ;)",

    "browser_action":
    {
        "default_icon":"icon.png"
    },
    "background":{
        "scripts":["background.js"]
    }
}

background.js

console.log("Hello World");

function yo(){
    console.log("yo");
}
chrome.browserAction.onClicked.addListener(yo);

After extensive googling, I did remove my popup from the manifest and also declared my script in the background of manifest, but still to no avail. How should I go about fixing this?

Thanks in advance
