I have a django template that I am including in another template. The included template has variables that need to be populated by a backend view. The view should only be called when a certain button is clicked which means that the template is rendered before it is populated by any of the view variables. How do I update the rendered template when the view is called which happens when the button is clicked. 

Some notes:
1. I don't want to use jquery so please use fetch() for the request
2. my view is currently returning the result of the render function, i.e. render(request, html\_template, context)
To achieve the desired functionality where a Django template is updated dynamically after a button click, you can use the Fetch API to make an asynchronous request to your Django view. Here’s a step-by-step guide on how to set this up without using jQuery:

### Step 1: Update Your Django View

Ensure your Django view can handle the request and return the rendered template snippet. You can create a separate view for this purpose, which returns only the HTML you want to update.

```python
from django.shortcuts import render
from django.http import JsonResponse

def my_view(request):
    # Your context data that you want to render
    context = {
        'variable1': 'value1',
        'variable2': 'value2',
    }
    html_template = 'your_template.html'  # The template you want to render
    rendered_template = render(request, html_template, context).content.decode('utf-8')
    
    return JsonResponse({'html': rendered_template})
```

### Step 2: Create Your Main Template

In your main template, include the button and a placeholder where the dynamic content will be rendered. Here’s an example:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Dynamic Template Update</title>
</head>
<body>
    <div id="content
A classic problem!

You're correct that the template is rendered before the view is called, which means you can't populate the template with the view's variables on the initial render. To update the template when the button is clicked, you'll need to use JavaScript to make an AJAX request to your view, and then update the template with the response.

Here's a suggested approach:

**1. Modify your view to return JSON data**

Instead of returning a rendered HTML template, modify your view to return a JSON response containing the data you want to populate in the template. You can use Django's built-in `JsonResponse` object for this:
```python
from django.http import JsonResponse

def my_view(request):
    #... perform some logic...
    data = {'variable1': 'value1', 'variable2': 'value2'}
    return JsonResponse(data)
```
**2. Add an event listener to the button**

In your HTML template, add an event listener to the button that will trigger an AJAX request to your view when clicked. You can use the `fetch` API for this:
```html
<button id="my-button">Click me!</button>

<script>
  document.getElementById('my-button').addEventListener('click', function() {
    fetch('{% url "my_view" %}')
     .then(response => response.json())
     .then(data => {
        // Update the template with the received data
        //...
      })
     .catch(error => console.error('
