Autofill For Enable Or Disable Fields With Js

Hi, i've done a query with result 0,1 for use with autofill function to enable or disable fields dimanically. For example I select something in the lookup and i get the right value dinamically for enable or disable fields (value 0 or 1). I've 2 fields to enable or disalbe NS (secret number) and CT (serial number). And this query works!

But my java wont't works correctly because it enable or disable fields function works right only at the second click press. any suggestion?
TD.on('change', function(e)

{

if (NS.getValue()== '1')

{

NS.setEnabled();

}

else

{

NS.setDisabled();

}
if (CT.getValue()== '1')

{

CT.setEnabled();

}

else

{

CT.setDisabled();

}
