Svelte 5 and this is undefined

Why I have for this input undefined? Type something and press tab or enter. Svelte is v5.1.3 and I am sure that something is missing..

<script lang="ts">    let abc11=$state("");    const izmjeni = (event: HTMLInputElement, data: string) => {        console.log(event);        console.log(data);    }</script><input    onchange={() => izmjeni(this, "apiData")}    bind:value={abc11}    type="text"/>
