You need to get the selection from the iframe. Here's how:

var cssApplier;
$("#ok_button").click(function()
{
    var iframe = document.getElementById("iframe_id");
    var iframeWin = rangy.dom.getIframeWindow(iframe);
    cssApplier.applyToSelection(iframeWin);

    // In Rangy 1.3, you can pass the iframe object directly into
    // applyToSelection so the previous two lines become:
    // cssApplier.applyToSelection(iframe);
});


$("iframe#iframe_id").load(function()
{
         rangy.init();
    cssApplier = rangy.createCssClassApplier("boldRed", {normalize: true});
});
