DataTables-show column data in modal

I have a column in my table that is a long string. So i'm trying to show it in a popup modal.

When i click the button to launch the modal, the page just refreshes and nothing is even printed to console.

HTML of Modal:

<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h3 id="modalTitle"></h3>
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
            </div>
            <div class="modal-body"></div>
            <div class="modal-footer">
                <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
            </div>
        </div>
    </div>
</div>

Here is snippet in DataTable creation.

{ data: 'Journal',
        render: function(data, type, row) {return '<button class="btn btn-primary" data-toggle="modal" data-Journal="'+data+'" data-target="#myModal">'+"Details"+'</button>'} },

The modal show event. Nothing is printed in console so i'm guessing the error is before here.

$("#myModal").on('show.bs.modal', function (e) {
    var triggerLink = $(e.relatedTarget);
    var journal = triggerLink.data("Journal");
    console.log(e.relatedTarget);
    console.log(journal);
    $("modalTitle").text("Title");
    $(this).find(".modal-body").html("<h5>"+journal+"</h5>");});

Try changing your button to type = button as its default is submit'

    render: function(data, type, row) {return '<button class="btn btn-primary" data-toggle="modal" data-Journal="'+data+'" type="button" data-target="#myModal">'+"Details"+'</button>'} },

Since you didn't provide any relevant details regarding your use case, I've made up my own example, which delivers major idea, though:

//make up random source for DataTable
const tableSrc = [...Array(5)].map((item, index) => {
  const rowObj = {};
  rowObj.user = 'user'+(index+1);
  rowObj.ip = [...Array(4)].map(() => Math.floor(Math.random()*140)+10).join('.');
  rowObj.hash = [...Array(256)].map(() => String.fromCharCode(Math.floor(Math.random()*(126-33))+33)).join('');
  return rowObj;
});
//initialize DataTable
const dataTable = $('#mytable').DataTable({
  sDom: 't',
  data: tableSrc,
  columns: [
    {title: 'Username', data: 'user'},
    {title: 'IP address', data: 'ip'},
    {
      title: 'Hash',
      data: 'hash',
      render: data => `<span>******</span><button class="showhash">show</button>`
    }
  ]
});
//display 'hash' property for particular row upon clicking the button
$('#mytable').on('click', 'button', function(){
  const clickedRow = dataTable.row($(this).closest('tr'));
  const modalTitle = `Hash for ${clickedRow.data().user}`;
  const modalBody = clickedRow.data().hash;
  $('#mymodal .modal-title').text(modalTitle);
  $('#mymodal .modal-body').text(modalBody);
  $('#mymodal').modal('toggle');
});

td button {
  float:right
}
