Cancel on modal confirmation dialog not working

Question

I have a simple modal popup dialog launched on the "register" button of a "new element" form :

$( "#ctl00_m_g_9ff78e92_ed40_4212_ae0f_44b787664fa8_ctl00_toolBarTbl_RightRptControls_ctl00_ctl00_diidIOSaveItem" ).click(function() {


            if (confirm("Confirmez-vous ce choix de réforme ? : ")) {

             }
             else {
                 return false;
             }


    });

})

The dialog is launched but the "Cancel" doesn't work: the element is created anyway.

I've tried different way of returning the false method but same problem each time.

EDIT

$(document).ready(function(){

$( "#ctl00_m_g_9ff78e92_ed40_4212_ae0f_44b787664fa8_ctl00_toolBarTbl_RightRptControls_ctl00_ctl00_diidIOSaveItem" ).click(function() {


        function PreSaveAction() {   
           if (confirm("Confirmez-vous ce choix de réforme ? : ")) {
                return true;
           }
           else {
                return false;
           }
        }
         //OpenConfigurationDialog("Confirmez-vous ce choix de réforme ?");


        PreSaveAction();


    });

})

Override the PreSaveAction in order to cancel the save.

    function PreSaveAction() {   
       if (confirm("Confirmez-vous ce choix de réforme ? : ")) {
            return true;
       }
       else {
            return false;
       }
    }
