React Dom not updating after updating a state array

so this function updates this state array:
let [Produits, setProduit] = useState(JSON.parse(Devis.produits))

 let changeQte = (id, e) => {
    let produittable = Produits;
    produittable.forEach((p) => {
      if (p.id == id) {
        p.quantityAchete = parseInt(e.target.value);
      }
    });
    setProduit(produittable);  
  };

the array did update without any problem but the changes aren’t getting re-rendered

  {console.log('rendering') ,Produits.map((p) => (
            <div key={p.id} className="product_column flex_center">
              <div className="productItem">{p.nom}</div>
              <div className="productItem">{p.category}</div>
              <div className="productItem">{p.prix_vente} DA</div>
              <input
                onChange={(e) => changeQte(p.id, e)}
                type="number"
                name="qte"
                value={p.quantityAchete}
              />

as you can see i’m loggin to the console to check if that line is getting executed and it does ! but the values rendered doesn’t update !
