Initialize Workflow(start from Share dashlet)

[molti]

As it is possible initialize value bpm_assigne, what at start workflow - it has been already chosen as the executor ?
I try this code, but doesn't work as it is necessary

<start-state name="start">
   <task name="sw:submitATask" swimlane="initiator">
    <event type="task-create">
              <script>
            <variable name="bpm_assignee" access="write"/>
            <variable name="people" access="read"/>
            <expression>
               bpm_assignee = null;
               var assignee = people.getPerson("Nachalnik");
               bpm_assignee = assignee;
            </expression>
         </script>
      </event>
      </task>
      <transition name="" to="next"/>
   </start-state>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Whether probably to insert a similar script before start workflow manually??????

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wf:review";
workflow.parameters["bpm:workflowDescription"] = document.name;
workflow.parameters["bpm:assignee"] = person;
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 7);
workflow.parameters["bpm:workflowDueDate"] = futureDate; 
workflow.execute(document);
