Why is $this->winners variable an emtpy array after ajax call

Hi everyone!
I'm using snippets to draw a table of 6, let's say, lottery winners.
I'd like to have a button to choose the prize of a specific winner.

So…what does the code look like?
At start the user has an empty page with a button to draw the 6 winners. The button works fine.

public function handleDrawWinners()
	{
		$response = $this->getHttpRequest()->getPost()['drawWinners'];
		if ($response == 'all') {
			$this->template->winners = $this->winners = $this->getWinnersInfo($this->getWinners(true));
		}
		$this->redrawControl('raffleWinners');
	}

Afterwards I draw rows of winners where each row has a button to choose a prize manually.

{snippet raffleWinners}
<table class="table">
		<thead>
			<tr>
				<th>Name</th>
				<th>Prize</th>
				<th>Choose prize</th>
			</tr>
		</thead>
		<tbody>
		{foreach $winners as $winner}
			<tr>
				<td>{$winner['name']}</td>
				<td>{$winner['prize']}</td>
				<td>
					<button class="btn" id="prizeManual{$winner['card_id']}" data-prize="{$winner['prizeKey']}" data-card="{$winner['card_id']}">Zvolit cenu manuálně <i class="la la-gift"></i></button>
				</td>
			</tr>
		{/foreach}
		</tbody>
</table>
{/snippet}

So I get the id after a button click which I send to php which works fine as well. The issue is that I need to work with $this->winners because I need to modify only one row but when I dump it, it's empty.

public function handleChangePrize()
	{
		$response = $this->getHttpRequest()->getPost()['changePrize'];
		bdump($response);
		bdump($this->winners);
	}

I think I could probably just send all 6 winners in JSON to the JS event listener which would then pass it to the handler but I want to know why this happens and if there isn't a better solution.
