Counter inside aura:iterator

Hi All,

I want to use counter inside aura: iterator. Like below

<aura:attribute name="counter" type="integer" default="0"/>

<aura:iteration items="{!v.futureInteractions}" var="Interaction">
  <aura:if istrue="{!v.counter =0 && Interaction.isFutre}">
      Futre interaction
     <aura:set attribute="counter" value="1" />

Can anyone help me how can i change counter value inside iterator???
Best Answer chosen by Aman nema
calculate and set counter attribute in javaScript controlller/helper not in Lightning component 
doInit : function(component, event, helper) {
	  var futureInteractions = component.get("v.futureInteractions");
      var counter = component.get("v.counter");
       var finalCount = 0;  
        for(var i = 0; i < futureInteractions.length; i++){
            if(futureInteractions[i].isFutre && counter == 0){
     component.set("v.counter" , finalCount);   

inside aura:iteration only itrate values
