I have a xxx.html.twig file which shows a page, but when I want to refresh the page with different data and just update it with new data, I have a select and a submit button for it. The thing is that I don't know how do I call an action in the controller which I pass parameters to from my twig and call for new data and then I render the same twig template again with new parameters.

How do I do so?

You can only do this using a new request. If you don't want to load the whole page, have a look at Ajax. – Sgoettschkes
You should extend your question with code examples and specify places, where you want pass what – Vitalii Zurian

Symfony 2.1:

{% render 'YourBundle:YourController:yourAction' with {'var': value} %}

Symfony 2.6+:

{{ render(controller('YourBundle:YourController:yourAction', {'var': value})) }}

And, of course, read the documentation.

Here are a few different ways:

{{ render(app.request.baseUrl ~ '/helper/test', {"hostid2": hostid } ) }}

or

{% include 'MyCoreBundle:Helper:test.html.twig' with {"hostid2": hostid } only %}

or

{% render controller("MyCoreBundle:Helper:test", {'hostid2': hostid}) %}

I think some parts are depricated here. To make the include work in latest Symfony 3.1.10, I solved it like this:

{% extends 'base.html.twig' %}
{% block body %}
    {{ include('AppBundle:Default:inner_content.html.twig') }}
{% endblock %}

Note: include() with parentheses. Then all the variables are included from the parent template. If you like to restrict some variables in the child template, you use with ... only (look over)
