Hi Rohit,

Try this.. on function to attach the event listener to the radio button element.

require(["dojo/query", "dojo/on", "dojo/domReady!"], function(query, on) {
  // Replace "radioButtonID" with the unique ID or class of your radio button element
  var radioButton = query("#radioButtonID")[0];

  // Attach the event listener to the radio button
  on(radioButton, "change", function() {
    // Access the selected value of the radio button
    var selectedValue = radioButton.value;

    // Perform your desired actions based on the selected value
    // For example, you can log the selected value to the console
    console.log("Selected value: " + selectedValue);
  });
});
I hope it help you.
