Twitch number online streamers in Chrome Plugin

API
12

Hi,
I change name from popup.js to background.js. Effect the same, and no errors in consol :[

When I put code like this:

var clientID = 'API-key';
var baseKraken = 'https://api.twitch.tv/kraken/';

function getKrakenAPI(endpoint, data, method) {
	return $.ajax({
			url: baseKraken + endpoint,
			method: method,
			data: data,
			dataType: 'json',
			headers: {
				'Client-ID': clientID,
				Accept: 'application/vnd.twitchtv.v5+json'
			}
		});
}

getKrakenAPI(
		'streams',
		{
			channel: [ 'ivelios_christopher', 'esl_sc2' ]
		}
	)
.done(function(data) {
		if(data._total > 0) {

    

		}
	});

chrome.browserAction.setBadgeText( { text: "On" } );

The text “On” display normal. I don`t get it. In “If” not working, but solo without “If” in, working normal :[

Best,
Ivelios
