Jquery Template does not work on HTTPS page

I have an AJAX function that works on several pages, except for a page that uses HTTPS:

$.ajax({
    url : url,
    type : "get",
    async: false,
    success : function(result) {

       console.log("Status AJAX: " + result.resultStatus);
       if(result.resultStatus == 'SUCCESS'){
           $('#div-select-filter-ligth-box').html(
               $('#select-ligth-box-template').tmpl({
                   lista : result.list
                })
           );
       }
       return false;
    },
    error: function() {
       console.log('AJAX Error');
    }
 });

I have already debugged the function and the AJAX returns this data. Does anyone know the cause of this problem?
