What are the relevant tickets?

None

What's this PR do?

This will allow to upload the files, as of now if we try to use file upload function, it does not work. After this change it works back to normal

How should this be manually tested?

Just try to upload the file with this change and without this change.

Where should the reviewer start?

It's a minor .js file change so shouldn't be much effort

Any background context you want to provide?

I was trying to upload the file by using this block for one of the clients and it did not work .

After some digging around I found this error TypeError: $.post(...).success is not a function

Which lead me to https://stackoverflow.com/questions/46394793/typeerror-post-success-is-not-a-function

Hey @ichintanjoshi,

I was trying to reproduce the issue but I could not. I tried Firefox and Opera with a local Devstack setup.

Could you please share more details on your environment? Have you tried reproducing it locally with Devstack OR Tutor?
Thanks!
