I have a asp.net page with two jquery button.

All is in an updatepanel. When I click on Jquery button all work but after all stops to work. Icons on button disappear and not responding to click event.

This is code of one button:

$(document).ready(function () {
        $("#btCerca").button({
            icons: {
                primary: 'ui-icon-search'
            }
        }).click(function () {
            document.getElementById("<%= btnRicerca.ClientID%>").click();
            return false;
        });

Reading around forum I'have found a partial solution. using .live method

This is the new code:

 $(document).ready(function () {

        $("#btCerca").button({

            icons: {

                primary: 'ui-icon-search'

            }

        }).live('click',function () {

            document.getElementById("<%= btnRicerca.ClientID%>").click();

            return false;

        });

        $("#cmdAnnulla").button({

            icons: {

                primary: 'ui-icon-squaresmall-close'

            }

        }).live('click', function () {

            document.getElementById("<%= btnAnnulla.ClientID%>").click();

            return false;

        });

    });

So my problem is icons on button. They disappear after the first click. 

How I solve it?
