I am pretty new to vue js. I need to render the value returned by the following function to the row in the table:

The function is:

getGroup(id){
        this.users.forEach(element =>{
            if(element.id===id)
                return element.group.group_name;
        });
}

The html tag in template is:

<td>{{ getGroup(ticket.assignee.assignee_id) }}</td>

However, nothing is rendered in that column respective rows. How can I show the value returned in those rows?

The full code is here:

<template>
<div >
    <table>
        <thead>
            <tr>
                <th >Subject</th>
                <th >Requester</th>
                <th >Requested</th>
                <th >Type</th>
                <th >Priority</th>
                <th >Group</th>
                <th >Updated</th>
                <th >Assignee</th>
                <th >Cause of suspention</th>
            </tr>
        </thead>
        <tbody>
            <tr v-for="ticket in tickets" :key="ticket.id">
                <td>{{ ticket.subject }}</td>
                <td>{{ ticket.requester }}</td>
                <td>{{ ticket.requested }}</td>
                <td>{{ ticket.type }}</td>
                <td>{{ ticket.priority }}</td>

                <td>{{ getGroup(ticket.assignee.assignee_id) }}</td>

                <td>{{ ticket.updated }}</td>
                <td>{{ ticket.assignee.assignee_name }}</td>
                <td>{{ ticket.suspension_cause }}</td>

            </tr>
        </tbody>
    </table>
</div>

<script>
import usersData from '../assets/users_data.json'
import ticketsData from '../assets/tickets_data.json'

export default {
    name: 'ViewTicket',
    data() {
        return {
            users:[],
            tickets:[],
            group: ''
        }
    },
    methods:{
        getData(){
            setTimeout(function(){this.users=usersData;}.bind(this),1000);
            setTimeout(function(){this.tickets=ticketsData;}.bind(this),1000);
        },
        getGroup(id){
            this.users.forEach(element =>{
                if(element.id===id)
                    return element.group.group_name;
            });
        }
    },
    created:function(){
        this.getData();
    },
};
</script>

Try to find and return user group:

getGroup(id){
  return this.users.find(u => u.id === id).group.group_name
}
