Livewire array property resets

In a livewire component i want to add/remove item id's(or any data) into an array. But when i dump the array i see:

• It is every time the $ticked array is empty first and then the new value added. But previous changes does not remain.

my component class looks like this

class MyComponent extends Component
{
    public $ticked = array();
	...
	public function settick ($id)
    {   
		dump($this->ticked);
        $index = array_search($id, $this->ticked);
        if ($index !== false)
        {
            unset($this->ticked[$index]);
        }
        else
        {
            array_push($this->ticked, $id);
        }
        dump($this->ticked);
    }			
}

and this is the view part

@foreach($items as $item)
  <div>
	<p> {{ $item->name }} </p>
    <input type="checkbox" wire:click="settick({{ $item->id }})">
  <div>
@endforeach

and this is the output of dump() calls

//first dump
[]
//second dump when I click the checkbox of $item->id => 14
array:1 [▼
  0 => 14
]
// it adds 14 to the array, but there should be previous changes in the array but is empty when functions executes

sorry, this might be a dumb question but i couldn't understand why.

Update

• Okay, the problem was dump() calls :).
• so, now i am using

{{ count($ticked) }} 

• for debugging (whether $ticked array changed or not).
• It would be good if someone could explain why i shouldn't or how to use dump() in livewire method.
