Are there any important considerations to creating signals in control component callbacks like For

      <For each={props.data}>
        {(data) => {
          const [isOpen, setOpen] = createSignal(false);
          return <Component data={data} isOpen={isOpen} onClick={()=>setOpen(x=>!x)}/>;
        }}
      </For>

      <For each={props.data}>
        {(data) => {
          const [isOpen, setOpen] = createSignal(false);
          return <Component data={data} isOpen={isOpen} onClick={()=>setOpen(x=>!x)}/>;
        }}
      </For>
