Jquery Optimization for multiple filters

I have the code below on an internal site I've built to handle some php generated table data. The data is a mix of int, string, and date, sometimes with markup in rows. The code all works, and it's relatively quick already, but sometimes javascript will break and none of the filters will work. It won't throw any errors in firebug. All are in a (document).ready statement in an external js file. I've added comments before each statement that describe what they do. All filters trigger a row count that I tried, unsuccessfully, to make into a method.

//moves a graph from the bottom of the page where php puts it to the top.
//Clears the original DIV
var moving = $("#mover").html();
  $("#mover").html('');
  $("#target").html(moving);

 //changes rows from red to green based on value
  $(".late").each(function(){
  var daySince = $(this).text();
  var dateCheck = parseInt(daySince);
  if(dateCheck<30&&daySince.toLowerCase().indexOf("xx")===-1){
  $(this).css("color","#3FFF00");}
    });

  //filters rows on anchor click
$("#openOnly").click(function(){
    $("tr").each(function(){
        $(this).removeClass("hiddenCS");
    });
    $(".toCloseMark").each(function(){
        $(this).addClass("hiddenCS");
    });
    var rowCount = $("tr:visible").length - 1;
    $("#matching").val(rowCount).change();
});


  //filters rows on anchor click
$("#closedOnly").click(function(){
    $("tr").each(function(){
        $(this).removeClass("hiddenCS closedMark");
    });
    $("tbody tr").not(".toCloseMark").each(function(){
        $(this).addClass("hiddenCS");

    $("#matching").val(rowCount).change();

    $("#matching").val(rowCount).change();

 //removes some formatting that de-emphasizes some rows
  $("#shower").click(function(){
    $(".toCloseMark").each(function(){
      if($(this).hasClass('closedMark')){
        $(this).removeClass('closedMark');
        $("#shower").html("Reduce Closed");
