Filter a repeater using multiple input components

I’m trying to create a custom filter connected to a dynamic list.

I found this article https://www.wix.com/velo/example/mega-search and I copied the code and modified it according to my needs.

I only changed my parameters, the code is exactly the same.

Everything works except the price sliders.

Someone can help me?

This is my code:

import wixData from 'wix-data';
import { debounce } from 'lodash';

const collectionName = 'macchine';
const debounceTime = 500;

$w.onReady(function () {
    initComps();
    initRepeater();
    buildFiltersAndPopulateRepeater();
});

async function initComps() {
    // populate iLocation dropdown
    const res = await wixData.query(collectionName)
        .ascending('marca')
        .distinct('marca')
        .then((locationData) => {
            return locationData.items.map((location) => {
                return {
                    value: location,
                    label: location
                }
            });
        });
    $w('#dropMarca').options = res;

    // change max price according to type selection
    $w('#iAnticipo').onChange((event) => {
        $w('#iPrezzoMax').max = event.target.value === 'Sì' ? 2000 : 3000;
    });

    // bind all input elements
    const componentsTypeArray = ['RadioButtonGroup', 'Dropdown', 'Slider', 'CheckboxGroup'];

    const debounceFunction = debounce(buildFiltersAndPopulateRepeater, debounceTime);
    componentsTypeArray.forEach((compType) => {
        const compArray = $w(compType);
        compArray.forEach((comp) => {
            comp.onChange((event) => {
                debounceFunction();
            });
        });
    });
}

async function buildFiltersAndPopulateRepeater() {
    let dataQuery = wixData.query(collectionName);

    dataQuery = dataQuery.eq('anticipo', $w('#iAnticipo').value);
    if ($w('#dropMarca').value) {
        dataQuery = dataQuery.eq('marca', $w('#dropMarca').value);
    }

    // sliders
    dataQuery = dataQuery.ge('prezzo', $w('#iPrezzoMin').value);
    if ($w('#iPrezzoMin').value > 0) {
        dataQuery = dataQuery.le('price', $w('#iPrezzoMax').value);
    }

    // multiple selection
    $w('#iCheckbox').value.forEach((selectedOption) => {
        dataQuery = dataQuery.eq(selectedOption, true);
    })

    $w('#repListaAuto').data = await dataQuery.find().then((res) => res.items);
}

function initRepeater() {
    $w('#repListaAuto').onItemReady(($item, itemData) => {
        $item('#immagineMacchina').src = itemData.foto;
        $item('#nomeMacchina').text = itemData.nomeauto;
        $item('#cavalliMacchina').text = String(itemData.cavalli);
        $item('#anticipoMacchina').text = itemData.anticipo;
        $item('#prezzoMacchina').text = '$' + String(itemData.prezzo);
    });
}

This is my dataset:
