Detect sub tab list click on a suitelet

Hi guys,

I have a suitlet with a list if sub tab lists.

Need to detect when the user clicks a sub tab list.

I tried to use JQuery a few ways on the page init:

function clientPageInit(type){

    //custpage_prov tab
    jQuery( "#custpage_prov" ).click(function() {
          alert( "Handler for .click() called." );
        });

    jQuery( "#custpage_provtxt" ).click(function() {
          alert( "Handler for .click() called." );
        });


    jQuery( "#custpage_provlnk" ).click(function() {
          alert( "Handler for .click() called." );
        });

}


no alert displayed on click.

Any ideas ???

Many thanks,
Marcel
