#### 🔅 Example

In this example, we define a simple frontend component that includes an "ontest" event. When the user clicks the "handle on server" button, 
the Python side's ontest event handler will process it and receive data passed from the frontend component. Meanwhile, when the "Modify Data" 
button on the Python side is clicked, the frontend component will respond by changing the displayed content.
