jQuery Datatables - Tooltipster not working on page 2

Question

I have an issue using the Tooltipster with the jQuery datatable. The tooltip only works on the first page and doesn't work on the subsequent pages.

UPDATE: My js is

$('#tblCurrentEnrollments')
        .on('order.dt', function () {
            $('.demo-interact.tooltipstered').tooltipster('destroy');
            setTimeout(SetToolTipster, 500);
        })
        .on('search.dt', function () {
            $('.demo-interact.tooltipstered').tooltipster('destroy');
            setTimeout(SetToolTipster, 500);
        })
        .on('page.dt', function () {
            $('.demo-interact.tooltipstered').tooltipster('destroy');
            setTimeout(SetToolTipster, 500);
        })
        .on('length.dt', function () {
            $('.demo-interact.tooltipstered').tooltipster('destroy');
            setTimeout(SetToolTipster, 500);
        })

        .dataTable({
            "bAutoWidth": false, // Disable the auto width calculation
            "lengthMenu": [[5, 10, 25, 50, -1], [5, 10, 25, 50, "All"]],
            "aaData": currentEnrollments,
            "aoColumns": [
                {
                    "mData": getToolTip,
                    "sWidth": "30%"
                },
                {
                    "mDataProp": "_Class.class_title",
                    "sWidth": "30%"
                },
                {
                    "mDataProp": "EnrollmentResults.enrollment_results_title",
                    "sWidth": "20%"
                },
                {
                    "mDataProp": "ecommerce_time",
                    "sWidth": "20%"
                }
            ]
        });

function getToolTip(data, type, dataToSet) {
var link = "www.google.com";
var tipDesc = '';

tipDesc = data.Course.course_description;
tipDesc += "<p><a href='" + link + "' target= '_blank'>Click this link</a></p>";
tipDesc += "<p><img src='images/lion.jpg' /></p>"

return '<div class="demo-interact" title="' + tipDesc + '">' + data.Course.course_title + '</div>';
}

The code above is working. I would like to know if this could be shortened or made any more cleaner that what it is right now.

Thanks.

If you're using dataTable pagination with Tooltipster and your tooltips aren't available in the DOM at the point in which $.fn.tooltipster() is called your subsequent un-initialised tooltips on other dataTable "pages" are not going to work.

Since you've not included the code for Tooltipster here I'm going to make a few assumptions, but an idea would be to call your Tooltipster init function e.g. something like $('.tooltip').tooltipster(), for each of the dataTable "page" next and previous clicks, and not just in your $(document).ready() (yet another assumption).

Update: (following your updated comment)

In that case, you'll need to utilise a DataTable parameter called fnCreatedCell. This will allow you to modify the DOM element after mRender has made it available, this amended segment of your original DataTable configuration should do the job:

"aoColumns": [{
    "mDataProp": "Course.course_title",
    "sWidth": "30%",
    "mRender": function (data, type, full) {
            // alert(currentEnrollments.length());
            tipDesc = "Test"; //data.course_description;
            tipDesc += "<p><a href='" + link + "' target= '_blank'>Click this link</a></p>";
            tipDesc += "<p><img src='images/lion.jpg' /></p>"

            return '<div class="demo-interact" title="' + tipDesc + '">' + data + '</div>';
        }
    },
    "fnCreatedCell": function (nTd, sData, oData, iRow, iCol) {
        $(".demo-interact", nTd).tooltipster({
            // Your Tooltipster config. here
        });
    },
    {
        "mDataProp": "_Class.class_title",
        "sWidth": "30%"
    },
    {
        "mDataProp": "EnrollmentResults.enrollment_results_title",
        "sWidth": "20%"
    },
    {
        "mDataProp": "ecommerce_time",
        "sWidth": "20%"
    }
]

I hope this helps :)
