I am working on a module where i have generated few DOM elements dynamically. But when i am trying to call certain function on some events then its not getting called. Here is the code sample. Here you can see i am calling getData method on "change" event but its not being called

getData: function() 
 var data = this._super();
 data.additional_data.bank_type = $('input[name="payment\[bank_type\]"]:checked').val();
 data.additional_data.emi = $('input[name="payment\[emi\]"]:checked').val();
 data.additional_data.email = this.getEmail();
 console.log($('input[name="payment\[emi\]"]:checked').val());
 return data;
 ,

 getEmi: function (emiCount) 
 var total = priceUtils.formatPrice(quote.totals().grand_total, quote.getPriceFormat());
 var rowTotal = quote.totals().grand_total;
 var item = '';
 var html = '';
 var i;
 for (i=1; i<=emiCount; i++ ) 
 if (i==1) 
 item = "<li>" +
 "<input type='radio' name='payment[emi_type]' data-bind='event: change: getData' id='emi" + i + "' value='" + i + "'>" +
 "<label class='label' for='emi" + i + "'>Tek Ödeme, Toplam: "+total+"</label>" +
 "</li>";
 else 
 rowTotal = parseInt(rowTotal)/i;
 item = "<li>" +
 "<input type='radio' name='payment[emi_type]' data-bind='event: change: getData' id='emi" + i + "' value='" + i + "'>" +
 "<label class='label' for='emi" + i + "'>"+i+" Taksit, Aylık Taksit: "+priceUtils.formatPrice(rowTotal, quote.getPriceFormat())+" Toplam: "+total+"</label>" +
 "</li>";
 
 html = html+item;
 

 console.log(html);
 $('.emi-list').html(html);
 ,

You did not mention on which html element you are trying to call change event.Can you tell me more about binding template.

I used js code like.

 return this;

 ,

 alert(

 );
 var jsonTempStringified = JSON.stringify(data);

 var fid = jsonTempStringifiedParsed.fid;
 var data = 'fid':fid;

);

Binding template .html file.
