ansible playbook with jinja2 loop

I need to write a playbook using jinja2 tamplate inorder to write firewalld rule in ansible. For that I wrote

---
- name: Firewalld check
  hosts: localhost
  become: yes

  tasks:
  - name: Allow ICMP traffic
    firewalld:
      rich_rule: rule family='ipv4' source address=" {{ source }} " protocol value="icmp" accept
      permanent: no
      state: enabled

in template and

---

- name: Firewalld config
  hosts: localhost
  become: yes

  vars:
    source:
       - 172.16.2.114
       - 172.16.2.115
  tasks:

  - name: Rules
    template:
      src: playtem.yml.j2
      dest: playbook.yml

in playbook. The output I expected is

---
- name: Firewalld check
  hosts: localhost
  become: yes

  tasks:
  - name: Allow ICMP traffic
    firewalld:
      rich_rule: rule family='ipv4' source address="172.16.2.114" protocol value="icmp" accept
      permanent: no
      state: enabled
  - name: Allow ICMP traffic
    firewalld:
      rich_rule: rule family='ipv4' source address="172.16.2.115" protocol value="icmp" accept
      permanent: no
      state: enabled

but the outcome which came is

---
- name: Firewalld check
  hosts: localhost
  become: yes

  tasks:
  - name: Allow ICMP traffic
    firewalld:
      rich_rule: rule family='ipv4' source address=" [u'172.16.2.114', u'172.16.2.115'] " protocol value="icmp" accept
      permanent: no
      state: enabled

So could anyone help me to solve this problem please?
