LinkButton click event not firing asp.net

I dont know why linkbutton onclick event is not firing. I have tried rewriting the code. I have tried to redirect directly on button click function. I have tried setting a break point inside dashbut_Click() on redirectUser() line but it never reaches there. Kindly help me figure this out.

HTML:

<li><asp:LinkButton ID="dashbut" runat="server" 
           CausesValidation="false" 
           OnClick="dashbut_Click"
           Text="Dashboard">
               <img src="images/dash.png" height="25" width="25" class="fa fa-tachometer" /><span> Dashboard</span>
    </asp:LinkButton>
 </li>

Code Behind:

protected void dashbut_Click(object sender, EventArgs e)
{
    //Response.Redirect("~/Views/Portal/AdminDashboard.aspx");
    redirectUser();
}

private void redirectUser()
{
    string myConnection = dbController.connectionString;
    SqlConnection conn = new SqlConnection(myConnection);

    string userCheckQuery = "SELECT UserType from tblUsers where ID = '" + USERid + "'";
    SqlCommand cmd1 = new SqlCommand(userCheckQuery, conn);
    conn.Open();
    bool userType = (bool)cmd1.ExecuteScalar();
    conn.Close();

    if (userType == true)
    {
        Response.Redirect("~/Views/Portal/AdminDashboard.aspx");
    }
    else if (userType == false)
    {
        Response.Redirect("~/Views/Portal/Dashboard.aspx");
    }
}

EDIT:

It seems that the LinkButton click event is not firing because of a JS Error. I dont know how that is related but when I click on the button and view the error on browser Inspect Element I see the following TypeError.

Uncaught TypeError: theForm.submit is not a function
at __doPostBack (NewArtist.aspx:63)
at <anonymous>:1:1

This is the script:

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['form1'];
if (!theForm) {
    theForm = document.form1;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
//]]>
</script>

Error is on theForm.submit(); line.

This is beyond me. Help me out.

So the problem seemed to be with JavaScript. Actually there was a button on my page with ID=submit this was overriding submit() function on the form, hence the error. This helped Thumbs Up for Stackoverflow Community.

Sorry if I can't comment due to low reputation points. I would like to know if you need CauseValidation set to false.

Try adding usesubmitbehavior="false".
