Two gujarati number addition and return value in gujarati

I installed Gujrathi input tool from google, but it takes numbers in Roman only. I even went to try it out tab and selected language gujrathi and typed and still shows roman number. What am i doing wrong?

 

But if i select Marathi, i see proper marathi number. 

input using goole input tool in two textbox gujarati language

 

when click button both textbox addition and display result gujarati language and also english language

Can you show an example of Gujrathi numbers you have. You have typed roman numbers here.

 

Where are they stored what format? How are you getting input?
