The subreport is not displayed in the master report - jasper-reports

Question

I'm new to jasperreport and currently I don't know how to display sub in master. I searched a lot on this site but i didn't solve my problem.
First, let me note that I load the data from the database in java because I need it later for certain filters...Here is code of class and main.
Class List_A
public class List_A {
private Integer ID_list_A;
private String sektorSvojine;
private String namjenaKoriscenja;

private Integer brojObjekta;
private Integer broj;
private String plan;
private String skica;

private double povrsina;

private String koRazmjera;
public List_A(String sektorSvojine, String namjenaKoriscenja, String osnovni, String podbroj, Integer brojObjekta,

Here is code for Master and Subreport, and how it looks like.

Picture how looks Subreport
When I just want to display the subreport then it fills everything and it's ok, but when I want to display it in the master, only the static text that I have appears, and that's it, the subreport does not appear at all...
Here's what it looks like when I run them separately Subreport and Master
I know i need to do something with the subreport parameters but i can't figure out what... help would mean a lot to me, I will appreciate it.
