Description

When creating a new application from the global application listing, for selecting the associated account, if there are more than 20 accounts then there a link "view all accounts" is displayed. When clicking on that link, a pop-up view with accounts is displayed. This pop-up account list view has a search filter called "find an account". That search filter is not working since it looks a dead button (no network/request activity when clicking it). This was working until 3scale 2.13 version but from 2.14 version it is not working anymore (including latest 2.15.3). See screenshots.

Issue impact
When having a high number of accounts (i.e. 2k) the creation of a new application from the global application list now requires going through more than 400 pages of accounts for selecting the right account from the pop-up view, which makes this action almost non-operational.

Current behavior
The search in Select an Account in View all accounts pop-up view is not doing any action when trying to use it and hence it is not filtering any account in that pop-up account view.
This functionality stopped working from 3scale 2.14 version onwards.

Expected behavior
The search in Select an Account in View all accounts pop-up view works perform an actual search (like when it was working fine in 2.13 version)
