Update points at run time when clicked on imagebutton

Question

if user is satisfied with the answer  then he/she clicks on the imagebutton and that particular ans gets the point,this is stored in the Point table in database. Now I want that as soon as the user clicks on this imagebutton he/she should see points with an increment of plus(+) 1 at run time. Please note that user is able to see the total no. of points that particular answer has got before.Only thing that I am not getting is that user should see automatical update in the number of points at runtime when he/she clicks on the imagebutton.
