Can I set for loop value in components render?

Hi,I'm beginner in grapesjs. I want to make a question number by for loop when I dropped components, ↓I want final like this image. the div can show for loop number.

↓my component's code

 // default html
    const questionCom = 
   `<div class="gjs-row">
        <div class="gjs-cell">{{i}}</div>  //number variable
        <div class="gjs-cell"></div>
    </div>`;

    const dc = editor.DomComponents;
    const textType = dc.getType('text');
    editor.BlockManager.add('m2', {
            label: "question number",
            activate: true,
            content: {
                type:'m2',
                questionCom ,
         
            },  
        }),
        dc.addType('m2', {
            model: textType.model.extend({
                //...     
                }
            }),
            view:textType.view.extend({
                onActive(){
                    //...
                },
                render(val) {
                    var a=""
                    this.model.set('components', 
                          function a1(){  //on onActive I call function a1
                               for(var i=0;i<3;i++){ 
                                    a+=`<div class="gjs-row"><div class="gjs-cell">`+
                                           val+
                                           `</div><div class="gjs-cell"></div></div>`
                                }   
                                return a         
                            }
                       }
                      return this;
                },
            })
        });

In render, I divided the my default html questionCom from {{i}} into front and back. then,put them in render. {{i}} can perfect to show 1 2 3 in component.

but ,the divided method is not good. HTML can't easy to read and I can't set complex html if I want like↓

<div class="gjs-row"> //one div
        <div class="gjs-cell">  //two div
               <div class="gjs-row"> //three div
                        <div class="gjs-cell">{{i}}</div>  //four div
                        <div class="gjs-cell"></div>
                 </div> 
         </div> 
        <div class="gjs-cell"></div>
    </div>

Have any better method can solve my question? Thanks!
