Dropdown with dinamic data - how read text value?

Hallo
I use dropdown, with Dinamic data (values and texts loading from database) - JS.
All is OK, I can read value key but can not read text key of the selected item.
This is my code (when value key = 1 then submit button is disable).
inp_Country is dropdown, inp_submit_prof is Submit button.

window.addEvent('domready', function() {
   $('inp_Country').addEvent('change', function(){  
    $('inp_submit_prof').setProperty('disabled', false);
    if ( $('inp_Country').value == 1 ) {    
     $('inp_submit_prof').setProperty('disabled', true);
    };    
   });
});

Please help me how can I read text key?

Best regards
