Resolve wrong message during the selection of items by checkbox

In a list page If i checked the header checkbox, system showing wrong message "4 ITEM(S) SELECTED" but there only 3 items present

On a listing page there 3 items are present, but when I select the select all checkbox system showing 4 items is selected. There is a variable "countCheckedCheckboxes" that define the length of the table values. At first, I think if I decremented the countCheckedCheckboxes value 1 then it's OK.

But there is a problem if the counted total length value is always countCheckedCheckboxes -1 then the first checkbox length always be counted as 0(zero).

That why i set a new class on that count the lenght of content.


$(document).ready(function(){
        var checkboxes = $('input[type="checkbox"]'); 
        checkboxes.click(function(){
            var countCheckedCheckboxes = checkboxes.filter(':checked').length;
            if(countCheckedCheckboxes  > 0){
                $('.label_info').text(countCheckedCheckboxes-1+' item(s) selected');            
            }else{
                $('.label_info').text('No item selected');
            } 
        });
    });

    $(".checkSelect").change(function () {
  
    var lenghtCheck= $('input[class="checkSelect"]:checked').filter(':checked').length //that check the length of table content's
           //the variable lenghtCheck that count the length of table content.
            if( lenghtCheck > 0){
                $('.label_info').text(lenghtCheck+' item(s) selected');             
            }else{
                $('.label_info').text('No item selected');
            }
   });
