Thank you all for your guidelines.

Link( Changing text after an input field ) shared in comment helped me. It's slightly different but resolved my problem. Below is the code to resolve it.

var inputTaxCol = $("#" + newtaxColId + " :input");
                  text = inputTaxCol[0].nextSibling.nodeValue,
                  newText = text.replace(text, 'my new text here');
