jquery - Radio button with return false javascript still invoke onchange with old value -

I have a radio button that is bound to change the event and check its value. But when that radio button was also clicked for attachment, it is still implementing the change event with the clicked value.

How can I fix this problem so that he / she can call change or click change without the clicked radio button.

Thanks in advance.

so that the event handler is not attached to the radio button with readonly class Will be done.
