select_one and select_multiple in survey do not change on select

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a form def with multiple or single selection and test this form on 
the Survey app in any device

What is the expected output? What do you see instead?
On the device, when testing the form in Survey, changing the selection on a 
"select multiple" prompt, should have changed the styling of the active choice 
selected. Instead the currently selected choice stays active (blue) for 1 
second and than becomes inactive. On a select_one prompt, when selection for ex 
choice nr4 will keep this choice active for like 1 sec and after that it will 
change back to the default first value.  

What version of the product are you using? On what operating system?

Android 5 & Android 4.1

I got it - the problem occurred when the data_value in the choices worksheet 
were numeric. Works fine with a string data_value
