I am using the jquery-input-ip-address-control for helping with masking the IP address. I can get the change function to fire and I am not sure if it related to this control.

$(document).ready(function(){
    $('#txtstartIpAddr').ipAddress();
  $('#txtendIpAddr').ipAddress();
  
  $('#txtstartIpAddr').change(function(){
    console.log('dd');
  });
    
 function Function() {
        console.log('dd');
    }
});
