title: Customizing function in a standard js file of Fiori app
body: <p>I have requirement to customize a js file (statushandler.js) in a standard Fiori application (PMRoffers).
  I have read through the documentation and blogs for the same, and followed the below approach</p>
  <ol>
  <li>Copied the statushandler.js file into my extension project with the path similar to standard apps folder structure</li>
  <li>made reference to the extended file into the controllers calling the same, under sap.ui.define([])</li>
  </ol>
  <p>Tried to launch the extended app, I can see in the chrome debugger, the custom file is loading, however the functions within that is not getting called.
  Not sure if any  step is being missed , need your expert advice.</p>
  <p>Thanks.
  Regards,
