return html code from python script to html via flask (theory))

Question

I am just playing with python script (test.py) there is one function test1().

def test1(): 
    return '<button (code ... for one simple button) .... ></button>'

In my init.py:

from flask import Flask
from flask import render_template, url_for
import test

abc = test.test1()

app = Flask(__name__)
@app.route("/")
def index():
    try:
        return render_template('index.html', something=abc)
    except Exception as e:
        return str(e)

if __name__ == '__main__':
    app.run()

In my index.html I have:

<body>
    {{something}}
</body>

Why html doesn't consider this variable as a code? If i copy <button (code ... for one simple button) .... ></button> to index.html directly and i just call reneder_template(index.html), everything is fine, however if i call this string from test.py html acts this is pure text within body tags... is there a way to fix this? Would appreciate it. Bascially, i would like html to read this string as a code not as a text.
