Multifield using Sling Model

[Jangra98]

I have this following multifield component with field type text field and name property is ./text and multifield is composite. 

So, what will be the sling model for that to show the values on HTL?

<?xml version="1.0" encoding="UTF-8"?>

    jcr:title="multifield"
    sling:resourceType="cq/gui/components/authoring/dialog">

        sling:resourceType="granite/ui/components/coral/foundation/fixedcolumns">
        <items jcr:primaryType="nt:unstructured">
            <column
                jcr:primaryType="nt:unstructured"
                sling:resourceType="granite/ui/components/coral/foundation/container">
                <items jcr:primaryType="nt:unstructured">
                    <text
                        jcr:primaryType="nt:unstructured"
                        sling:resourceType="granite/ui/components/coral/foundation/form/multifield"
                        composite="{Boolean}true"
                        fieldLabel="Products">
                        <field
                            jcr:primaryType="nt:unstructured"
                            sling:resourceType="granite/ui/components/coral/foundation/container"
                            name="./products">
                            <items jcr:primaryType="nt:unstructured">
                                <name
                                    jcr:primaryType="nt:unstructured"
                                    sling:resourceType="granite/ui/components/coral/foundation/form/textfield"
                                    emptyText="Name"
                                    name="./text"/>
                            </items>
                        </field>
                    </text>
                </items>
            </column>
        </items>

I have tried with below Sling model -

package com.aem.demo.core.models;

import java.util.List;

import javax.inject.Inject;

import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;

@Model(
	    adaptables = {Resource.class},
	    defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public interface ProductsModel {

	@Inject
	  List<Product> getProducts(); // the name `getProducts` corresponds to the multifield name="./products"
	  /**
	   * Company model
	   * has a name and a list of departments
	   */
	  @Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
	  interface Product {
	    @Inject
	    String getText(); // corresponds name="./text"
	    
	  }
	  
}

.content.xml of cq:dialog -

                        sling:resourceType="granite/ui/components/coral/foundation/form/multifield"

                            sling:resourceType="granite/ui/components/coral/foundation/container"
                            name="./products">
                            <items jcr:primaryType="nt:unstructured">
