jquery tooltip doesn't display content on hover

I am trying to display table as a tooltip content.

However the table doesn't seem to show.

Here's the HTML:

<td>
    <a href="javascript:void(0);" data-toggle="tooltip1" class="red-tooltip" title="">5 Users</a>
</td>

The table:

<table id="tooltipContent" border="4" bordercolor="black" cellspacing="1" cellpadding="15px" style="width: 800px; display: none;">
     <tr><td>ravi_shrestha(r_sth@gmail.com)</td></tr>
     <tr><td>ravi_shrestha(r_sth@gmail.com)</td></tr>
     <tr><td>ravi_shrestha(r_sth@gmail.com)</td></tr>
</table>

Tooltip initialization:

"fnDrawCallback": function( settings ) {
    $('[data-toggle="tooltip1"]').tooltip({
         content: $('#tooltipContent').html()
    });                
 },

Putting something in title attribute itself is working though.

Solution

Try using a callback function, properly add the js and css dependencies

$('[data-toggle="tooltip1"]').tooltip({
         content: function() { return $('#tooltipContent').html();}
});

$('[data-toggle="tooltip1"]').tooltip({
  content: function() {
    return $('#tooltipContent').html();
  }
});
