Set the update property for app.js to full in app.json:

{
    // Path to file. If the file is local this must be a relative path from this app.json file.
    "path": "app.js",

    "bundle": true,  /* Indicates that all class dependencies are concatenated into this file when build */

    // If 'update' not specified, this file will only be loaded once, and cached inside
    // localStorage until this value is changed. You can specify:
    //   - "delta" to enable over-the-air delta update for this file
    //   - "full" means full update will be made when this file changes
    "update": "full"
}

Disable the cache in extjs so browser will get data from server. To do that, add the following app.json file.

"production": {
    "cache": {
        "enable": false
    }
}

"css": [
    {
        // this entry uses an ant variable that is the calculated
        // value of the generated output css file for the app,
        // defined in .sencha/app/defaults.properties
        "path": "${build.out.css.path}",
        "bundle": true,
        "update": "full"
    }
],
