javascript - Post in flask does not render new template

Let's say I have this setup

Why after clicking "arrToPython" button flask does not redirect me to "query_result.html"? And more importantly, how can I make it to do so?

I tried creating separate route like and using flask's "redirect" method, but it did not work for me either :(
test.py:

from flask import Flask
from flask import request, url_for
from flask import render_template
from flask import redirect, Response
app = Flask(__name__)
@app.route('/', methods=['POST', 'GET'])
def savingImage():
    if request.method == 'GET':
        return render_template('test.html')
    if request.method == 'POST':
        return render_template('query_result.html')
if __name__ == '__main__':
    app.debug = True
    app.run()

Where test.html

And query_result.html

 Hola amigo!
