Sharepoint hosted app custom list form upgrade

SharePoint2013

I created a SharePoint Hosted add-in with custom list form.

Works great until you want to upgrade the add-in with changes to your custom form.

here issue is when i modify any new code in my new page(Custom page), then i increased version and upgraded using app catalog,but which i modified new code is not showing it is showing old page code(before modification code).

please help me..

What I have tried:

I have tried the following approaches:

1.Created a module entry within the list element.xml with ReplaceContent=True which deploys successfully but does not replace the form with new changes.

2.Tried to reference a custom form page from Pages module but the Path in Schema.xml somehow keeps looking for the custom form within the List Definition folder.
