Try AutoCalculator https://github.com/JavscriptLab/autocalculate Calculate Inputs value and Output By using selector expressions

Just add an attribute for your output input like data-ac="(#firstinput+#secondinput)"

No Need of any initialization just add data-ac attribute only. It will find out dynamically added elements automatically

FOr add 'Rs' with Output just add inside curly bracket data-ac="{Rs}(#firstinput+#secondinput)"
