Why is the Django template file not updating value from the context?

Question

(I am a beginner in Django)

I am following along a tutorial in Django where we can dynamically pass some variable to a template file from associated function in views.py

When I am running the code for the first time, it works fine, but when I change the values within the context, the template does not update with the new values even when I refresh it

Here is my views.py code -

    from django.shortcuts import render
    from django.http import HttpResponse
    
    # Create your views here.
    def index(request):
        # return HttpResponse('<h1>Hey, welcome</h1>')
        # we can dynamically send data to our index.html file as follows -
        context={
            'u_name': 'Ankit',
            'u_age': 25,
            'u_nationality': 'Indian',
        }
        return render(request,'index.html',context)

Here is my template index.html -

<h1>
    How are you doing today {{u_name}} <br>You are {{u_age}} years old<br>Your nationality is {{u_nationality}}
</h1>

settings.py has been correctly set as well -

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR,'templates'],

Editing post to add urls.py as well (this is within the app)

from . import views
from django.urls import include,path

urlpatterns = [
    path('',views.index,name='index')
]

And the urls.py in the main project -

from django.contrib import admin
from django.urls import path, include


urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('MyApp.urls'))
]

Here is my output - does not take the values from the context

Would be glad if someone could point out what error I am making. Thanks in advance
