How to change the bootstrap caret pointing direction on click event

Question

I'm using 2.3.2 bootstrap

As I can change the position of the caret icon when I click the menu button.

I need that when I click the icon caret pointing up and when you click on another item the caret back to the initial state.

How is this possible?

The nav code

<div id="navi">
    <div class="container">
      <nav>
        <div class="navbar">
          <div class="navbar-inner">
            <div class="row">
              <button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
              </button>

              <div class="span2">
                <a class="brand" href="#"></a>
              </div>

              <div class="span10">
                <div class="nav-collapse collapse">
                  <div class="row">
                    <div class="span8">
