i've solved similar issue base on this solution. need check element twbspagination, , if exists destroy it.

var total_pages = data; var logid = '30';  if($('#pagination').data("twbs-pagination"))   $('#pagination').twbspagination('destroy');   $('#pagination').twbspagination({   totalpages: total_pages,   visiblepages: 7,   onpageclick: function (event, page) {       $('#container').load('load_data.php',{page:page,id:logid});   } });  $('#container').load('load_data.php',{id:logid});
