WordPress Cron not triggering a Jquery action

I am trying to create an automatic emailer which sends reports once per month. I already created a cron event which triggers every minute (for testing purposes only) and it works fine.

Now the problem that I am facing is I’m currently using a plugin which generates and exports a csv file, I want to reuse it’s function to generate a report then send it to email. This exporter plugin is designed to trigger once a button is clicked.

Here’s my current code for the cron scheduled event function.

function update_db_hourly() {
    global $wpdb;
    $wpdb->insert(
        'rtl21016_cron',
        array(
            'test' => 'value1'
        )
    );
    testing();
}

And here’s the testing function which contains some jquery codes.

function testing(){
	global $wpdb;
    $wpdb->insert(
        'rtl21016_cron',
        array(
            'test' => 'value2'
        )
    );
    ?>
    <input type="button" value=" Export Report " id="auto_report" class="button" style="display:block; position:absolute; z-index:100; top:500; right:100" onclick="window.open('?page=exports-reports&report=4&action=export&export_type=csv&export_source=custom_monthly_reports','temp_report_window');">
    <iframe name="temp_report_window" id="temp_report_window" class="temp_report_window"></iframe>
    <script>console.log("Send RTL reports...");jQuery('#auto_report').trigger('click');</script>
    <?php
    global $wpdb;
    $wpdb->insert(
        'rtl21016_cron',
        array(
            'test' => 'value3'
        )
    );
}

The jquery event in the function works whenever I manually call the function testing(). But whenever the cron scheduled event triggers it doesn’t work. the $wpdb->insert codes that you see there is for debugging purposes only, they all works just fine on all scenarios.

Any idea about this? Thanks in advance
