[web2py] jQuery on button click

[Diego R]

Hello,

I'm following instructions on video "16 Final Reddit clone improvements by 
Massimo" and I'm having problems calling jquery on button click:

Here is my code:

{{for post in row:}}
    <div class="alert alert-info">
        <table>

            <tr data-id="{{=post.id}}">

                <td><button data-direction="up">+</button></td>

                <td><span class="votes">{{=post.votes}}</span></td>

                <td><button data-direction="down">-</button></td>

                <td><strong>&nbsp;{{=A(post.title, _href=post.url) if 
post.url else post.title}}</strong><br/></td>

          </tr>
          <tr><td colspan = "3"></td>

              <td>{{=A('comments', _href=URL('view_post', args = 
post.id))}}</td>

          </tr>
      </table>
    </div>
{{pass}}


<script>

function do_ajax_vote(t,direction) {
        alert('clicked');
    }

    
    jQuery(function(){
        jQuery('[data-direction=plus]').click(function() 
{do_ajax_vote(this, 'up');});
        jQuery('[data-direction=minus]').click(function() 
{do_ajax_vote(this, 'down');});
    });
</script>

When I click the buttons, nothing happens, no popup. My pop-ups are not 
blocked. I'm not sure what I'm doing wrong... 

Thanks in advance!
