Hi,I wanted to excute inner <aura:if> only once.I'm unable to set the attribute value to false.Help is appreciated.

<aura:attribute name="native" type="boolean" default="true"/>
    <aura:attribute name="accounts" type="Account[]"/> 
    <div class="pink">
    <table style="width:100%">
        <aura:iteration var="acc" items="{!v.accounts}">
            <aura:if isTrue="{!acc.Id != ' '}">
            <aura:if isTrue="{!v.native}">
            <tr>
                <th>Account Id</th>
                <th>Name</th>
                <th>Country</th>
                <th>City</th>
                <th>Email</th>
            </tr>
                {!v.native}=false;
                 component.set("v.native",'false');
                 {!v.native};
            </aura:if>
            <tr>
                <td>{!acc.Id} </td> 
                   <td>{!acc.Name} </td> 
                   <td>{!acc.Country__c} </td>
                   <td> {!acc.City__c} </td>
                   <td>{!acc.Email__c}</td>            
            </tr>
            </aura:if>
      </aura:iteration>
    </table>  
    </div>

It doesn't work.Unable to change the value from 'true' to 'false'.Is there any solution to excute <aura:If> only once.
I wanted to view <th> (table header) only once.

Hii shivram,

You are doing mistake in your code  in this line ,
  {!v.native}=false;
  component.set("v.native",'false');
your both of above line won't work inside component directly.  
In .cmp file only HTMl, and expression will work but u can't use this method inside the .cmp file.
if you want to  change the value of your attribute u need to do this using controller , define an event call the javascript code and change the value of  your attribute.

For your query of getting header element only once i did this coding : 
<aura:component controller="OpportunityController">
    <aura:attribute name="opportunities" type="Opportunity[]"/>
    <aura:attribute name="check" type="Boolean" default="true"></aura:attribute>
    
    <ui:button label="Get Opportunities" press="{!c.getOpps}"/>
      <table>
         <tr>
          <th><b>Name</b></th>
          <th><b>Close Date</b></th>  
          <th><b>Owner</b></th>
          <th><b>Stage Name</b></th>
          </tr>       
              <aura:iteration var="opportunity" items="{!v.opportunities}">
                   <tr style="color:red;">
                       <td>{!opportunity.Name}</td> 
                       <td>{!opportunity.CloseDate}</td>
                       <td>{!opportunity.Owner.Name}</td>
                       <td>{!opportunity.StageName}</td>
                   </tr>    
                </aura:iteration>
             
    </table>
</aura:component>
 And my below screenshot is the result.

this is the result

Hi Rishav,
I really appreciate your help.But i want to change the value of attribute on the .cmp file itself without using the client controller .
Anything else do you want to suggest?
RishavRishav
I know only one thing before doing anything we need to understand the basics of that. If we are clear with that then we can go ahead. 
I don't know anything beyond this, so can't suggest you

                <th>Country</th>
                <th>City</th>
                <th>Email</th>
            </tr>
                {!v.native}=false;
                 component.set("v.native",'false');
                 {!v.native};
            </aura:if>
            <tr>
                <td>{!acc.Id} </td>
