Get form value in dynamic Template

How can i get the values of the form inputs in a dynamic template that consist of different templates/steps with multiple input values? I know that this can be done with helpers on each template but for flexibility reasons I would like to keep each step’s form values(and not create multiple helpers for all these different form inputs) , in the formData element of the instance.steps object so that to further check whether they have been filled in etc can that be done and how?
I wrote the helper function in formData in order to get the value of the id driving_license which is in the template stepTwo as you can see below, I cannot get anything thought, I also tried

` dl= parseInt($(‘input[name=```“driving_license”]:checked’).val())
but it also does not give me anything.

Template.experiment.onCreated(function () {


    const instance = this;
    instance.step = new ReactiveVar('stepOne');
    instance.steps = {
      formData:{
        'change #driving_license':async function (event, instance){
          event.preventDefault();
          dl=parseInt($(event.target).val(), 10)
          console.log('dl',dl)
          return dl
        },
      },
      stepOne: {
        nextStep: 'stepTwo',
        title: 'Start',
      },
      stepTwo: {
        step:'stepTwo',
        nextStep: 'stepThree',
        title: 'Next Part'
        
      },
      stepThree: {
        nextStep:'stepFour',  
        title:'Next',

      },
      stepFour: {
        message: '<h2>You did it, you finished all steps</h2>',
      },
    };

{{>Template.dynamic template=stepTemplate data=stepData }} ```
<template name="stepTwo">
<div class="form-check-inline">
 <label class="form-check-label">
<input type="radio" class="form-check-input" name="driving_license" id="driving_license" value="1">Yes
 </label>
</div>
<div class="form-check-inline">
<label class="form-check-label">
 <input type="radio" class="form-check-input" name="driving_license" id="driving_license" value="2">No
 </label>
 </div>
</template>

How have you attached the event listener for change #driving_license?
Is this all of the template related code that you’ve posted?
If so, you are likely just missing a Template.experiment.events block
