using insert and delete in a single page in jsp

using insert and delete in a single page in jsp

I am using the following code in jsp to declare two javascript functions to insert and delete in a single jsp page but insert function doesn't works only delete function works even if the insert button is clicked.. So what is wrong with the code?.. If there is some other way than please tell me.

function insert()
        {
          <%
        Connection con = null;
        cat=request.getParameter("cat");
    code=request.getParameter("code");
        det=request.getParameter("det");
        charge=request.getParameter("charge");
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
        con = DriverManager.getConnection("jdbc:odbc:Hospital","Santosh"," ");

 PreparedStatement psadd=null;
    String sqladdRecord=null;


    try
    {
        sqladdRecord="insert into wards values(?,?,?,?)";
        psadd=con.prepareStatement(sqladdRecord);
        psadd.setString(1,cat);
  psadd.setString(2,code);
  psadd.setString(3,det);
  psadd.setString(4,charge);
        psadd.executeUpdate();
    }
    catch(Exception e)
    {
      response.sendRedirect("Wards.jsp");

    }

    try{
      if(psadd!=null)
      {
       psadd.close();
      }

      if(con!=null)
      {
       con.close();
      }
    }
    catch(Exception e)
    {
      e.printStackTrace(); 
    }
%>
function Delete()
        {
          <%
        Connection conn = null;
        cat=request.getParameter("cat");
    code=request.getParameter("code");
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
    con = DriverManager.getConnection("jdbc:odbc:Hospital","Santosh"," ");

    PreparedStatement psdel=null;
    String sqldelRecord=null;


    try
    {
        sqldelRecord="delete from wards where category='"+cat+"' and code='"+code+"'";
        psdel=con.prepareStatement(sqldelRecord);

        psdel.executeUpdate();
    }
    catch(Exception e)
    {
      response.sendRedirect("Wards.jsp");

    }

    try{
      if(psdel!=null)
      {
       psdel.close();
      }

      if(conn!=null)
      {
       conn.close();
      }
    }
    catch(Exception e)
    {
      e.printStackTrace(); 
    }
