Passing value from ui page to ui action

[R9]

Hello,

I have a UI page with a dialog box. The dialog box takes in two values that I want to pass on to the UI action and then redirect from the UI action page to use these values to create an incident form. I tried calling the function in the UI action from the UI page but it does not work. 

UI PAGE

HTML- 

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

<j:set var="jvar_pref" value="${sysparm_incID}"/>

 <!-- <input type="hidden" id="rec" name="rec" value="${jvar_pref}"/>  -->

    <style>

        #jelly-div{

            width: 300px;

        }

    </style>

    <div id="jelly-div">

      <!-- Creation of Incident -->

 <g:ui_form id="incident">

    <input type="hidden" id="incID" name="incID" value="${sysparm_incID}"/>

  <h5>Assignment Group:</h5> <g:ui_reference id="assignment_group" name="assignment_group" table="sys_user_group" query="active=true" completer="AJAXTableCompleter" onchange="setUserFilter()"/><br/>

  <!-- <h5>Assigned To:</h5> <g:ui_reference id="assigned_to" name="assigned_to" table="sys_user" query="active=true" completer="AJAXTableCompleter"/><br/> -->

  <h5>Short Description:</h5> <input type="text" id="short_description" name="short_description" /><br/>

  <g:dialog_buttons_ok_cancel ok="return continueOk()" cancel="return continueCancel()" />

 </g:ui_form>

<!--End Incident-->

    </div>

</j:jelly>

Client Script-

function continueOk() {

     GlideDialogWindow.get().destroy();

    alert('continue ok');

    var assgn_group = gel(assignment_group).value;

    alert(assgn_group);

    var s_description = gel(short_description).value;

    alert(s_description);

  // updateTask();

    return gsftSubmit(null, g_form.getFormElement(), 'ws_create_incident_int');

}

function continueCancel() {

    alert("inside cancel");

    GlideDialogWindow.get().destroy();

    return false;

}

UI action

function showDialogimsInc() {

    var dialogClass = GlideDialogWindow;

  //  var gDialogInc = new dialogClass('sn_itsm_workspace_InteractionClosure_Popup');

    var gDialogInc = new dialogClass('sn_itsm_workspace_sow_native_incident_button');

    gDialogInc.setTitle('Interaction: ' + g_form.getValue('number'));

    gDialogInc.setPreference('sysparm_sys_ID', g_form.getUniqueValue());

    gDialogInc.setPreference('sysparm_type', 'inc');

    //gDialogInc.setPreference('dialogTrap', true);//

    gDialogInc.render();

}

if (typeof window == 'undefined')

    updateTask();

function updateTask() {

    current.state = 'closed_complete';

    if (current.update()) {

    var inc = new GlideRecord("incident");

    inc.initialize();

    inc.caller_id = current.opened_for;

    inc.short_description = current.short_description;

    inc.u_on_behalf_of = inc.caller_id; // point of contact autopopulated from impacted user

    if (current.type == 'chat') {

            inc.contact_type = 'Chat';

        } else if (current.type == 'messaging') {

            inc.contact_type = 'Chat';

        } else if (current.type == 'phone') {

            inc.contact_type = 'Phone';

        } else if (current.type == 'video') {

            inc.contact_type = '';

        } else if (current.type == 'walkup') {

            inc.contact_type = 'Walk-In';

        } else if (current.type == 'Email') {

            inc.contact_type = 'Email';

        }

//add an entry in the interaction_related_records table

    var incSysId = inc.insert();

    var interactionRelatedGR = new GlideRecord("interaction_related_record");

    interactionRelatedGR.initialize();

    interactionRelatedGR.interaction = current.sys_id;

    interactionRelatedGR.document_table = 'incident';

    interactionRelatedGR.document_id = incSysId;

    interactionRelatedGR.insert();

    action.openGlideRecord(inc);

}
