Chrome Extension Query : Related to Content Scripts

Question

Here is a code snippet from my Manifest.json :

"content_scripts": [
        {
        "matches" : ["*://www.google.co.in/flights/*"],
        "js" : ["myScript.js"]
        }
    ],
    "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'",
 "permissions": [
    "<all_urls>",
    "*://www.google.co.in/flights/*",
    "tabs"
   ]

/* myScript.js */

console.debug("Hi I am Content JS");

Now if i go to google flights page and open developer tool box then in console section shouldn't I see the above console.debug() message. I am not getting it where am I going wrong.
