Hello All,
I'm extremely new to lightning components and trying to replace some of our custom javascript buttons with lightning compatible options.  One button takes ownership of a lead.  I found a post that does something similar for cases and tried to modify it for my purpose: https://learnownlightning.blogspot.com/2018/01/change-owner-update-record-using.html

It seems to be doing the record update based on apex code, but it launches a quickaction screen with a cancel button that doens't go away.  I've seen it posted that you can use 

$A.get("e.force:closeQuickAction").fire();

It is not working for me.  I'm not sure if I'm not puting that code in the right place but I'm hoping someone can help me figure out a way to click the quick action button, have the lead change ownership, and that's it.

Here is my code so far:
Component:

<aura:component implements="force:lightningQuickAction,force:hasRecordId" controller="LightningComponent_MoveToMarketing" access="global" >
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>    
</aura:component>

Controller:

({
 doInit : function(component, event, helper) {
        var leadId = component.get("v.recordId");
        var action = component.get("c.changeOwnerMethod");
        action.setParams({
            leadId : leadId
        });
        action.setCallback(this, function(response) {
            if(response.getState() === "SUCCESS") {
                console.log("Lead Owner Changed To Current login User");
             var rec = response.getReturnValue();
             console.log(rec.OwnerId);
            }
        });
        $A.enqueueAction(action);
$A.get("e.force:closeQuickAction").fire();
        $A.get('e.force:refreshView').fire();
 }
})

Apex Class:

public class LightningComponent_MoveToMarketing {

    @AuraEnabled
    public static Lead changeOwnerMethod(Id leadId) {
        if(leadId != null) {
            Lead l = [SELECT OwnerId FROM Lead WHERE Id = :leadId];
         l.OwnerId = UserInfo.getUserId();
//update case Ownerid with loggedin userid.
            update l;
            return l;
        }
        return null;
    }

}

Any ideas?
