jquery and asp.net button click problem

I am using jquery tabs in asp.net web page. like this-

                           
• tab1"  class="active">

                           
• tab2

                           
• tab3

                       

                           
                           


i have a asp.net button control in which clientclickevent() i am validating some text boxes and giving tab title like this   $("#tab1").text(" test title");
tab contain a repeater control.

 OnClientClick="if (!enable_tabs()) {return false;}"   onclick="btn_find_trains_Click" /> 




when i click on the button initially tabs show the title but when the data binds in repeater control , title dissappears,

i tried update panel but nothing happens.

Any suggestions
