jQuery/ColdFusion Ajax Creating Session Variable

I am trying to create a Single Page Application using ColdFusion and JQuery. I am trying to have a (Print Labels) button that when it is clicked it will open up a bootstrap modal asking a question "Please enter label start number:" This textbox I want to somehow create a session variable that may be used on the (dealerlabels.pdf) pdf that opens Upon hit of Accept of the Bootstrap Modal. In the console.log(data) I am getting the correct response showing the number that was entered into $("#LabelNum") but I am unable to create the session variable. When I do a cfdump nothing exists in the struct. Will someone please tell me what I am doing wrong?

$(document).ready(function () { // What happens when a user hits the "Accept" button on the dealer form $(".label_accept").click(function () { $('#LabelMaker').modal('hide'); }); $('#labelForm').on('submit', function (e) { e.preventDefault(); alert($(this).serialize()); $.ajax({ // the location of the CFC to run url: "index_proxy.cfm", // send a GET HTTP operation type: "post", // tell jQuery we're getting JSON back dataType: "json", // send the data to the CFC data: $('#labelForm').serialize(), // this gets the data returned on success success: function (data) { console.log(data); if (data !== "") { var link = "DealerLabels.cfm"; window.open(link,'newStuff'); } }, // this runs if an error error: function (xhr, textStatus, errorThrown) { // show error console.log(errorThrown); } }); }); });
