                    $("#auto-complete-tag").addClass('loader');
                    var givenUserName = $("#auto-complete-tag").val();
                    $.post(urlHolder.getconnectedusersByName, {
                        userId : signedUserId,
                        username : givenUserName
                    }, function(response) {
                        $('#auto-complete-tag').removeClass('loader');
                        if(!response){
