jquery - Count many text inputs and do something when each is set -

i have many many textbox inputs on page, i'm attempting check each set in loop, when each set i'm attempting run function.

i have following code:

$( document ).ready(function() {  var count_input = 0; var count_valid_input = 0;   $("#weekly-suppliers").change(function(){             call_calculation(); //     });      function call_calculation(){             $('input[class=enquiry]').each(function(){                 count_input ++;                 var text_value = $(this).val();                 if(text_value != '') //remember, data has been sanitized!                 {                     count_valid_input ++;                     console.log('input: ' + count_input);                     console.log('valid: ' + count_valid_input);                 }             })             if(count_input == count_valid_input){                 console.log('do calc');                 do_calculation();             }             else {                 count_input = 0;                 count_valid_input = 0;             }         } }); 

this loops through each text input class enquiry. counter incremented each element, counter initiated each element set. if these 2 counters match, function run. i'm nevver reaching point though, suggest why?

the function call_calculation called in each text input change event. have lots of these functions in script, each text input:

 $("#weekly-suppliers").change(function(){                 call_calculation(); //         }); 

so when number of valid inputs matches number of text inputs class enquiry, function do_calculation(); should called, never met. suggest why?
