If you are sending data using json you don't need to use Jinja2. You can simply try something like this:

@app.route('/_get_content/')
def _get_content():
    option_id = request.form['option_id']
    all_options = models.Content.query.filter_by(id=option_id)
    return jsonify({'data': [option.name for option in all_options]})

or define a method in your model something like to_json that returns a field or dictionary or ... and call it in your view.

@app.route('/_get_content/')
def _get_content():
    option_id = request.form['option_id']
    all_options = models.Content.query.filter_by(id=option_id)
    return jsonify({'data': [option.to_json() for option in all_options]})
