Dropdown: filterBy not working.

[castrovini85]

Describe the bug

After setting which property I want to filter from, the component still uses the label.

Environment

I saw it on my localhost and was able to reproduce it on stackblitz.

Reproducer

https://stackblitz.com/edit/nqejfj-qma9qg?file=src%2Fapp%2Fdemo%2Fdropdown-filter-demo.ts

Angular version

17.0.0

PrimeNG version

17.0.0-beta.1

Build / Runtime

Angular CLI App

Language

TypeScript

Node version (for AoT issues node --version)

20

Browser(s)

No response

Steps to reproduce the behavior

Here I add the filterText property to the countries example from the website.

I also changed the filterBy option on the HTML

When I search for '1' or '2', nothing shows up

If I search by anything that matches the labels, it is filtering

Expected behavior

After setting the filterBy to a property of the object, it should be filtering by it, not the label.

@castrovini85 you missed the documentation checked here https://primeng.org/dropdown#api.dropdown.props.filterFields

you have to mention filterFields with array like this. [filterFields]="['filterText']"

you can check it here, https://stackblitz.com/edit/nqejfj-jpabs9?file=src%2Fapp%2Fdemo%2Fdropdown-filter-demo.ts
