Why does updating a token with JavaScript not cause panels dependent on those tokens to refresh?

Hello,
I am having trouble understanding why a token update via JavaScript does not cause a panel that is dependent on that token to refresh. I have a date input called status_date that is configured to set a token tok_status_date during initialization (with today's date), and when it changes. JS file is as follows:

require([
        'jquery',
        'splunkjs/mvc',
        'splunkjs/mvc/simplexml/ready!'
], function ($, mvc) {

        // initialization
        var tokens = mvc.Components.get("default");
        document.getElementById("status_date").valueAsDate = new Date();
        tokens.set("tok_status_date",document.getElementById("status_date").value);

        $('#status_date').on("change", function (e){
                tokens.set("tok_status_date",document.getElementById("status_date").value);
        });
});

An HTML panel that I have configured will always show the value of tok_status_date, even when I update the value of the input.

<row>
    <panel>
        <html>
            <center><h1>$tok_status_date$</h1></center>
        </html>
    </panel>
</row>

I also have an XML panel whose search is dependent on tok_status_date, but it does not update whenever I change the value of the input:

<query>| makeresults | eval Day = strftime(strptime("$tok_status_date$","%Y-%m-%d"),"%d/%m/%Y") | table Day</query>

Why is this? Am I missing something in the JavaScript file?

Thank you and best regards,

Andrew

I've managed to solve the problem. I was only working with the "default" tokens when I should have also been using the "submitted" tokens. Here is the script that works:

 require([
         'jquery',
         'splunkjs/mvc',
         'splunkjs/mvc/simplexml/ready!'
 ], function ($, mvc) {

         // initialization
         var def_tok = mvc.Components.get("default");
         var sub_tok = mvc.Components.get("submitted");
         document.getElementById("status_date").valueAsDate = new Date();

         def_tok.set("tok_status_date",document.getElementById("status_date").value);
         sub_tok.set("tok_status_date",document.getElementById("status_date").value);

         $('#status_date').on("change", function (e){
                 def_tok.set("tok_status_date",document.getElementById("status_date").value);
                 sub_tok.set("tok_status_date",document.getElementById("status_date").value);
         });
 });
