Change Font Awesome Icon on Click, but return to original icon when next item is clicked

Question

I'm using Bootstrap 3 Panel's and have appended the Font Awesome Plus and Minus icons to the panel items. I'm looking for a way using Jquery to change the plus to a minus "onClick", then when another panel item is clicked I want that minus icon to change back to plus.

I have been experimenting with some Jquery and have come close. I think I might just be missing something simple here. It seems to work fine for a few clicks, then it starts confusing which class to switch back to. My HTML:

<div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingFive">
        <h4 class="panel-title"><a class="collapsed faq-links" data-toggle="collapse" data-parent="#accordion" href="#collapseFive" aria-expanded="false" aria-controls="collapseFive"><i class="fa fa-plus-square-o fa-2x"></i>&nbsp;&nbsp;Panel Title 1</a></h4>
    </div>
    <div id="collapseFive" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingFive">
        <div class="panel-body">
            <p>Panel body text</p>
        </div>
    </div>
</div>
<br />
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="heading13">
        <h4 class="panel-title"><a class="collapsed faq-links" data-toggle="collapse" data-parent="#accordion" href="#collapse13" aria-expanded="false" aria-controls="collapse13"><i class="fa fa-plus-square-o fa-2x"></i>&nbsp;&nbsp;Panel Title 2</a></h4>
    </div>
    <div id="collapse13" class="panel-collapse collapse" role="tabpanel" aria-labelledby="heading13">
        <div class="panel-body">
            <p>Panel body text 2</p>
        </div>
    </div>
</div>
<br />
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingFour">
        <h4 class="panel-title"><a class="collapsed faq-links" data-toggle="collapse" data-parent="#accordion" href="#collapseFour" aria-expanded="false" aria-controls="collapseFour"><i class="fa fa-plus-square-o fa-2x"></i>&nbsp;&nbsp;Panel Title 3</a></h4>
    </div>
    <div id="collapseFour" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingFour">
        <div class="panel-body">

    <div id="collapseFour" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingFour">
        <div class="panel-body">
            <p>Panel body text 3</p>
        </div>
     </div>
   </div>
</div>

And my Jquery looks like this:

//TOGGLE FONT AWESOME ON CLICK
 $('.faq-links').click(function(){
 $(this).find('i').toggleClass('fa-plus-square-o fa-2x fa-minus-square-o fa-2x')
 });
 $('.faq-links').blur(function(){
 $(this).find('i').toggleClass('fa-plus-square-o fa-2x fa-minus-square-o fa-2x')
 });

As you can see, I'm using click on one function, and blur on the next as the event listeners. What am I doing wrong here? I have a JSFIDDLE set up to further explain my issue.

Thanks in advance for any help.

Update: Shivali Patel's answer that worked for me:

$('.faq-links').click(function(){
var collapsed=$(this).find('i').hasClass('fa-plus-square-o');

$('.faq-links').find('i').removeClass('fa-minus-square-o');

$('.faq-links').find('i').addClass('fa-plus-square-o');
if(collapsed)
$(this).find('i').toggleClass('fa-plus-square-o fa-2x fa-minus-square-o fa-2x')
});

He created a variable based on collapse and used addClass and removeClass in addition to the toggleClass events. Great work Shivali.

This is happening because of blur event.
If you click outside of any accordion still blur event is called and changed the icons of relevant accordion.
