Event binding to buttons in FireFox requires an alert() box

Question

Hi there

I have a piece of javasacript code that searches through several iframes for buttons with specifi id's. When I find the button, I bind a click event to the button. This works perfectly fine in IE, but only works in Firefox if I alert something, and upon clicking ok on the alert box, the button clicks works fine. Here's my code

    $.each(iframe, function(index, ifrm) {

         // Add target="_blank" to text hyper links
         var hyper = null, hyperCount = 0;
         hyper = $(ifrm).contents().find("a");           
         hyperCount = hyper.length;
         for (var t = 0; t < hyperCount; t++) {
            if (!$(hyper[t]).attr("target")) {
               $(hyper[t]).attr("target", "_blank");
            }
         }
         // end here

         var tmp = $("#hdnButtonActions-" + index).val();
         if (tmp !== "") {
            var actions = tmp.split(",");
            for (var i = 0; i < actions.length; i++) {
               var button = actions[i].split("=");
               var id = button[0];
               var targetType = button[1];
               var target = button[2];
               var targetIndex = button[3];

               //var ctrl = null;


               if (targetType === "Page") {                                    
                  $(ifrm)
                     .contents()
                     .find("button[id='" + id + "']")
                     .bind('click', { inx: eval(button[3]) }, pageHandler);
               }
               if (targetType === "Link") {
                  $(ifrm)
                     .contents()
                     .find("button[id='" + id + "']")                  
                     .bind('click', { url: button[2] }, linkHandler);
               }
            }
         }
      });         


      function pageHandler(event) {
         $tabs.tabs('enable', event.data.inx);
         $tabs.tabs('select', event.data.inx);
         return;
      }

      function linkHandler(event) {
         window.open("http://" + event.data.url);
         return;
      }

The click events either allows for a user to navigate to a specific jquery ui tab, or navigate to an external url which opens in a new window
