How can we add reference qualifier in the UI action

[royi]

How can we use the reference qualifier in the UI action where I'm using the same modal code.

I need to show the service offerings based on service (Parent) 

if I select the service, it should show the service offerings related to that service. Is it possible ?

function onClick(g_form) {

    var fields = [
        {
            type: 'reference',
            name: 'business_service',
            label: getMessage('What is the Service ?'),
            mandatory: true,
            reference: 'cmdb_ci_service',
            referringTable: 'sc_task',
            referringRecordId: g_form.getUniqueValue(),
			//value: g_form.getValue('caller_id'),
			//displayValue: g_form.getDisplayValue('caller_id')
        },
        {
            type: 'reference',
            name: 'service_offering',
            label: getMessage('What is the Service offering?'),
            mandatory: true,
            reference: 'service_offering',
			//query : "caller_id=" + g_form.getValue("caller_id"),
			// query: 'parent='+fieldValues.updatedFields[0].value + '^service_status=operational',
            referringTable: 'sc_task',
            referringRecordId: g_form.getUniqueValue()
		    	
			//value: g_form.getValue('caller_id'),
			//displayValue: g_form.getDisplayValue('caller_id')
        }
    ];

    g_modal.showFields({
        title: "Enter the Service/Service offering below",
        fields: fields,
        size: 'lg'
    }).then(function(fieldValues) {
        g_form.setValue('business_service', fieldValues.updatedFields[0].value);
        g_form.setValue('service_offering', fieldValues.updatedFields[1].value);
        g_form.save();
    });
}

function onClick(g_form) {

    var fields = [

        {

            type: 'reference',

            name: 'business_service',

            label: getMessage('What is the Service ?'),

            mandatory: true,

            reference: 'cmdb_ci_service',

            referringTable: 'sc_task',

            referringRecordId: g_form.getUniqueValue(),

            //value: g_form.getValue('caller_id'),

            //displayValue: g_form.getDisplayValue('caller_id')

        },

        {

            type: 'reference',

            name: 'service_offering',

            label: getMessage('What is the Service offering?'),

            mandatory: true,

            reference: 'service_offering',

            //query : "caller_id=" + g_form.getValue("caller_id"), @@@ I WANT TO ADD THE REFERENCE QUALIFIER HERE TO SHOW THE REALTED SERVICE OFFERINGS OF SERVICE

            // query: 'parent='+fieldValues.updatedFields[0].value + '^service_status=operational',

            referringTable: 'sc_task',

            referringRecordId: g_form.getUniqueValue()

            //value: g_form.getValue('caller_id'),

            //displayValue: g_form.getDisplayValue('caller_id')

        }

    ];

    g_modal.showFields({

        title: "Enter the Service/Service offering below",

        fields: fields,

        size: 'lg'

    }).then(function(fieldValues) {

        g_form.setValue('business_service', fieldValues.updatedFields[0].value);

        g_form.setValue('service_offering', fieldValues.updatedFields[1].value);

        g_form.save();

    });
