reflex Image upload

Hi Developers!

I have a problem with upload for pictures reflex does not have dynamic page reload. When a file with a photo is placed and saved in the database, it is dynamically added to the bottom of the page (for testing) and I noticed that when you add pictures, they are not displayed on the screen. But when you reload the server - everything is there. Agree, this is not convenient to add a gallery - you need to reload the page, which is not very convenient, especially if the project is already in operation. Tell me where my mistakes are?

Code:

from datetime import datetime
from sqlmodel import select, Field
from typing import Optional
import uuid


class Image(rx.Model, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    filename: str = Field(max_length=255)
    caption: str = Field(max_length=500)
    path: str = Field(max_length=255)
    created_at: datetime = Field(default_factory=datetime.utcnow)

class State(rx.State):
    """The app state."""
    images: list[Image] = []
    caption: str = ""
    processing: bool = False
    progress: int = 0
    
    def on_load(self):
        """Load existing images on page load."""
        with rx.session() as session:
            self.images = session.exec(
                select(Image).order_by(Image.created_at.desc())
            ).all()

    @rx.event
    async def handle_upload_progress(self, progress: dict):
        """Handle upload progress updates."""
        self.processing = True
        self.progress = round(progress["progress"] * 100)
        if self.progress >= 100:
            self.processing = False
            self.on_load()

            unique_filename = f"{uuid.uuid4()}.{file_extension}"
            
            
            upload_dir = rx.get_upload_dir()
