[Question] Is it possible to perform dom manipulation through the block's contents script?

Hey! First of all thank you so much to build such a great and versatile tool. Is it possible that I can manipulate the dom elements of the block through block's content script?

Eg.

 editor.BlockManager.add('open-question-2',  {
      id: 'open-question-2',
      label: `Open ended question 2`,

      category: 'Forms',
      attributes: {class:'fa fa-question-circle '},
      droppable: 'form',
      content:{
        content : `
          
        <div  data-id="question-container">
          <label>Question</label>
          <input type="textbox" class="form-control">
        </div>
        `,
        script : function(){
          $("div[data-id='question-container']").find("input").attr("value", "Enter you question here...")
        }

      }
    });

Basically I need a survey kinda block, where user can drop question block and then can enter the question string.

Once again thank you so much.
