LinkButton not calling a javascript function in IE

  Hi Guys,
  
  I have a linkbutton which calls a .net function which when clicked either displays or hides a DIV and changes an image. I also need this linkbutton to change the property of a javascript boolean variable.
  
  The javascript in place currently produces a popup notifying users that they have not completed their registration if they try to navigate away from the page without having submitted the form. All I need the linkbutton to do is to submit the following "needToConfirm = false;". By doing so, when the user clicks the linkbutton and the DIV is displayed/hidden (this refreshes the page) the javascript knows not to display the popup box as the user is staying on the page. This works fine in Firefox but not IE.
  
  I have added this to buttons, which work fine across both browsers, so it only the Linkbutton in IE that I am struggling.
  
  Below is my code:
  
  Client Side
  
  

  <asp:linkbutton id="lbViewAllProfessions"  runat="server"  önclick="lbViewAllProfessions_OnClick" xmlns:asp="#unknown">
  <asp:image id="imgIcon"  runat="server" imageurl="images/general/icon-plus.gif" /> view all job types
  

  
  
  Server Side
  Note: I have included the code for my working buttons below too.
  
  //This is in my Page_Load
  

  
  btnCandidateRegister.Attributes.Add("onClick", "needToConfirm = false;");
  btnFindAddress.Attributes.Add("onClick", "needToConfirm = false;");
  btnOKAddress.Attributes.Add("onClick", "needToConfirm = false;");
  btnCancelAddress.Attributes.Add("onClick", "needToConfirm = false;");
  lbViewAllProfessions.Attributes.Add("onClick", "needToConfirm = false;");
  //.Net function called by LinkButton
  protected void lbViewAllProfessions_OnClick(object sender, EventArgs e)
  {
  if (imgIcon.ImageUrl == "images/general/icon-plus.gif")
  {
  divSkillsBox.Visible = true;
  imgIcon.ImageUrl = "images/general/icon-minus.gif";
  }
  else
  {
  divSkillsBox.Visible = false;
  imgIcon.ImageUrl = "images/general/icon-plus.gif";
  }
  
  }
  

  
  
  Javascript
  

  
  <script language="JavaScript" type="text/javascript">
  var needToConfirm = true;
  
  window.onbeforeunload = confirmExit;
  function confirmExit()
  {
  if (needToConfirm)
  {
  needToConfirm = false;
  return "Your have not completed your registration process.";
  }else{
  needToConfirm = true;
  return;
  }
  }
  </script>
  

  
  
  I hope this is clear enough. Please let me know if you need anymore info.
  
  Thanks in advance,
  Martin

  Hi,

  Out of interest, does IE display any javascript errors when the link button is clicked?

  What happens if you put: java scipt:alert('test'); needToConfirm = false; in the attributes.add code?
