Function is not calling in livewire:click

When I try to increment/decrement the quantity nothing happens. My livewire component code below, class CartComponent extends Component { public $cartItems; public function mount() { $this->fetchCartItems(); }

public function fetchCartItems()
{
    $this->cartItems = Cart::where('user_id', Auth::id())->get();
}

public function incrementQuantity($cartId)
{
    $cartItem = Cart::where('user_id', Auth::id())
                     ->where('id', $cartId)
                     ->first();

    if ($cartItem) {
        $cartItem->increment('quantity');
        $this->fetchCartItems();
        $this->dispatchBrowserEvent('message',[
            'text' => 'Quantity updated',
            'type' => 'success',
            'status' => 200
        ]);
    } else {
        $this->dispatchBrowserEvent('message',[
            'text' => 'Something went wrong',
            'type' => 'error',
            'status' => 404
        ]);
    }
}

public function decrementQuantity($cartId)
{
    $cartItem = Cart::where('user_id', Auth::id())
                     ->where('id', $cartId)
                     ->first();

    if ($cartItem && $cartItem->quantity > 1) {
        $cartItem->decrement('quantity');
        $this->fetchCartItems();
        $this->dispatchBrowserEvent('message',[
            'text' => 'Quantity updated',
            'type' => 'success',
            'status' => 200
        ]);
    } else {
        $this->dispatchBrowserEvent('message',[
            'text' => 'Something went wrong',
            'type' => 'error',
            'status' => 404
        ]);
    }
}

public function removeItem($cartId)
{
    $cartItem = Cart::where('user_id', Auth::id())
                     ->where('id', $cartId)
                     ->first();

    if ($cartItem) {
        $cartItem->delete();
        $this->fetchCartItems();
        $this->dispatchBrowserEvent('message',[
            'text' => 'Item removed from cart',
            'type' => 'success',
            'status' => 200
        ]);
    } else {
        $this->dispatchBrowserEvent('message',[
            'text' => 'Something went wrong',
            'type' => 'error',
            'status' => 404
        ]);
    }
}


public function render()
{
    return view('livewire.cart', [
        'cartItems' => $this->cartItems,
    ])->extends('layouts.app');
}

}

My Blade file code is below

                    <span>{{ $item->quantity}}</span>

                    <button  type="button" wire:click="incrementQuantity({{ $item->id }})" wire:loading.attr="disabled">
                        <svg class="w-3 h-3" xmlns="http://www.w3.org/2000/svg" x="0px" y="0px" width="100"
                            height="100" viewBox="0 0 24 24">
                            <path fill-rule="evenodd"
                                d="M 11 2 L 11 11 L 2 11 L 2 13 L 11 13 L 11 22 L 13 22 L 13 13 L 22 13 L 22 11 L 13 11 L 13 2 Z">
                            </path>
                        </svg>
                    </button>
                </div>
                {{-- <div wire:loading wire:target="incrementQuantity, decrementQuantity" class="text-gray-500">Updating...</div> --}}
            </div>

What I checked already,

1. Livewire script in app.blade
2. Livewire working in another test file , So no point in livewire configuration.
