Validation does not work when field is clonable

Hi Tran,
I just found the same question asked before 1 year in general section but that seems closed thats why I am asking the same question again because my requirement is same now & validation for cloned field need to work.My problem is little different than previous discussion, there you said it breaks because of changing ID's so I have built my validation on the name attribute but in vain can you please help me?

The following function only works on first row but fails/no action on cloned rows

$("input[name$='fill-time\]'], input[name$='peak-pressure\]']" ).on("focusout", function (){
      viscosity = 0.0;
      shear_rate = 0.0;

      ins_ratio = $("#fm-intensification-ratio").val();
      fill_time = $(this).closest(".rwmb-row").find("input[name$='fill-time]']").val();
      pk_inj_press = $(this).closest(".rwmb-row").find("input[name$='peak-pressure]']").val();
      viscosity = parseFloat(ins_ratio) * parseFloat(fill_time) * parseFloat(pk_inj_press);
      viscosity = parseInt(viscosity,10);
      shear_rate = parseFloat(1 / parseFloat(fill_time)).toFixed(4);

      $(this).closest(".rwmb-row").find("input[name$='viscosity]']").val(viscosity);
      $(this).closest(".rwmb-row").find("input[name$='shear-rate]']").val(shear_rate);
      
  } );

Thanks & Regards,
Calpaq
