Component client lib not loading when called in workflow dialog participant step page

Hi,

I am new to AEM and using AEM 6.2

I created a component for touch UI, which has a checkbox (added  class="cq-dialog-checkbox-enabledisable" attribute) and  textbox (added class="cq-dialog-checkbox-enabledisable-target" atribute). I have added client lib to the hide/show textfield based on checkbox select and unselect. This works fine when i added the component to a page and tested.

I added touchUiDialogPath property /apps/sample/components/workflow/test/testlistener/cq:dialog and used the dialog in workflow  Dialog Participant Step. I started the workflow and in Dialog Participant Step CheckBox and TextField sowed up but TextField hide and shoe is not working. I noticed that my script itself did not get loaded when I did view source of the workflow page but script loaded for site/page. What is that I am missing here?

I see js files from etc, lib files getting loaded.

js code:

 /**
 * Extension to the standard checkbox component. It enables/disables  other components based on the
 * selection made in the checkbox.
 *
 * How to use:
 *
 * - add the class cq-dialog-checkbox-enabledisable to the checkbox element
 * - add the class cq-dialog-checkbox-enabledisable-target to each target component that can be enabled/disabled
 */
(function(document, $) {
    "use strict";

    // when dialog gets injected
    $(document).on("foundation-contentloaded", function(e) {
        // if there is already an inital value make sure the according target element becomes visible
        enableDisable($(".cq-dialog-checkbox-enabledisable", e.target));
    });

    $(document).on("change", ".cq-dialog-checkbox-enabledisable", function(e) {
        enableDisable($(this));
    });

    function enableDisable(el){
        el.each(function(i, element) {
            if ($(element).attr("type") === "checkbox"){
                if ($(element).prop('checked')){
                    //$('.cq-dialog-checkbox-enabledisable-target').enable();
                    $('.cq-dialog-checkbox-enabledisable-target').show();
                } else {
                    //$('.cq-dialog-checkbox-enabledisable-target').disable();
                    $('.cq-dialog-checkbox-enabledisable-target').hide();
                }
            }
        })
    }
})(document,Granite.$);
