[SalesForce] How to find which button in clicked in lightning

I'm creating a List that has one or more buttonIcons in the end.I'm creating these buttons dynamically with $A.createComponent.
While clicking the button,I need to find which button is clicked and then finding its position with getBoundingClientRect().
How can I do it?
I tried event.getSource(),event.currentTarget & event.target.
Nothing helped!
Or Is there any ways to find the position of a element in lightning.
(I need to show a popup relative to the button's position,can't use lightning:helptext)

First find the body of the parent component of the dynamically created components.
Then find the button and getBoundingClientRect Refer this QA,

findButton : function(cmp) {
        var parentElement = cmp.find("parent").get("v.body");
        console.log("child 1",parentElement[buttonIndex].find("buttonId").getBoundingClientRect());
    }

I feel like there should be a better solution, but one way to achieve what you're trying to do is to create a separate component to put inside your aura:iteration.

So, let's say you edit your aura:iteration to look like this:

<aura:iteration items="{!v.myObjects}" var="obj">
    <ak90:objectListItem item="{!obj}"/>
</aura:iteration>

And you create an objectListItem component that looks like this:

<!-- Attribute definition(s) -->
<aura:attribute name="item" type="ak90.myObject__c"/>

<!-- UI element(s) -->
<div>
    <ui:button label="{!item.ak90__Name__c}" aura:id="{!item.Id}" press="{!c.navToBar}"/>
</div>

In your c.navToBar() function, you'll be able to use component.get("v.item.Id") to figure out which specific button was pressed. From there, you can fire an event that includes the specific Salesforce ID corresponding to the pressed button, and then do what you need from there.

[SalesForce] Adding onclick to dynamically created button

I just did something like this the other day. Not sure if it meets all your needs but it at least illustrates the concept

Component Controller

({
doinit: function(component,event,helper){
    <iframe name="pc-frame" src="{!v.iframe-url}" style="width: 100%;height: 770px; border: none;" scrolling="true"/>

        $A.createComponent(
            "aura:html",
             { 
                 tag: "iframe",
                 HTMLAttributes:{
                     "id": "pc-frame",
                     "src": tmp, 
                     "scrolling" : "true",
                     "onload" : component.getReference("c.handlerFunction") //You can change to onclick if your html element supports it 
                 },
             }
                function(compo){
                    var container = component.find("container");
                    if (container.isValid()) {
                        var body = container.get("v.body");
                        body.push(compo);
                        container.set("v.body", body);
                    }
                }
        );

},

handlerFunction : function(component, event,helper){

    console.log('something');

}

)}
