Qlik Sense: Error in Navigation API. Binding to page

I asked this question on stack overflow with no success: javascript - Qlik Sense: TypeError: Cannot read property 'interactionState' of null - Stack Overflow

Background

In Qlik Sense I took the QS Table extension and slightly modified it so that if I add a dimention that is the name of the other sheets in the app you can navigate to them by qliking the td element.

My modifications to QS Table code:

// added to the create rows function
else if(~cell.qText.toLowerCase().indexOf('<sheet>')){
   var nameOfSheet = cell.qText;
  html += "QSsheetName' style='cursor: pointer;'"+'>'+nameOfSheet.slice(7, nameOfSheet.length)+'</td>';
}

// added a navigation function. Takes the text from the td element
// and then uses it to find out the Sheet Id of the sheet with that
// name and then uses the qlik.navigation api to go there.
var app = qlik.currApp();
function navigateToSheet ( sheetName ) { 
   var allSheets = {}; 
  app.getList('sheet', function(reply) { 
  $.each(reply.qAppObjectList.qItems, function(idx, value) { 
  allSheets[value.qData.title] = value.qInfo.qId; 
   }); 
   var mySheetId = allSheets[sheetName]; 
  qlik.navigation.gotoSheet(mySheetId); 
   }); 
};

// added a listener in the Paint section to call navigation function on qlik
$element.find("td.QSsheetName").on('click', function() {
  var elementText = $(this).text();
  navigateToSheet(elementText);
});

Problem

If I click on one of the td elements in the QS table to navigate to sheet A it does navigate to sheet A, the intended sheet. However, if I leave sheet A and go to sheet B and click on anything interactive, say a point on a line chart, then I am automatically sent back to sheet A. The console doesn't always produce an error but it does report the following error sometimes:

I added the line: console.log("table clicked")

to my jQuery listener but it doesn't log anything after I click the table the first time. So the random navigations are cached somehow and not calling my listener function above. Can anyone help with this?
