                    {{input type="hidden" name="MAX_FILE_SIZE" value="1048576"}}
                    {{input id="file" class="form-control" type="file" name="file" aria-describedby="file_help"}}

            </form>
        </div>
    </div>
</div>

components/post-edit.js

import Ember from 'ember';
import config from 'php-api-ember-test/config/environment';

export default Ember.Component.extend({
    actions: {
        addNew() {
            console.log('hit on submit button from add page');
            this.get('addNew');
        },
        editSave() {
            console.log('hit on submit button from edit page');
            this.get('editSave');
        }
    },
    addNew: Ember.computed(function() {
        console.log('adding new data');
        var formData = new FormData($('#form-add')[0]);
        this.get('ajax').request(config.APP.phpApiUrl+'/add', {
            method: 'POST',
        })
        .catch(function(error) {
            console.log(error);
            var response = error.errors[0].detail;
            console.log(response);
            // I want to call other component and render from here and put it in form-result-placeholder class.
            //console.log(Ember.Component.FormAlert);// undefined
            //$('.form-result-placeholder').html('{{form-alert}}');// not working
        });
    }),
    editSave: Ember.computed(function() {
        console.log('saving edit data');
    }),
    ajax: Ember.inject.service(),
    isEditing: false,
});

templates/components/form-alert.hbs

FORM ALERT!!! (this alert message will be change by ajax response. it is not static.)

components/form-alert.js

import Ember from 'ember';

const FormAlert = Ember.Component.extend({
});

export default FormAlert;

I want to call form-alert component from inside post-edit.js file after ajax request.
I want to call other component and render after ajax request and put it in form-result-placeholder class.
How to call Ember component from other component and render into target element?

My Ember version: 2.8.0

Take a look at this question. You need to use block form, and set the action on the child component.
