bootstrap 3 tooltip title function

Question

This is a dumb question I'm sure, but how can I pass a function to the tooltip for the title?

<span id="spanCount" data-toggle="tooltip" data-placement="bottom" title="" class="badge tip" data-original-title="getNames()">26</span>

The tooltip is just displaying the text "getNames()"

function getNames(){
            return 'testing';
        }

Answer 1

try data-title instead of data-original-title

<span id="spanCount" data-toggle="tooltip" data-placement="bottom" title="" class="badge tip" data-title="getNames()">26</span>

or via JavaScript

$('#mytooltip').tooltip({title: function(){return 'testing';} })
