How Do I Checked The Value Of (Radiobutton1.Checked == True) Dynamically ?

//global object for radiobutton1 is created for access all over to form
		static RadioButton RadioButton1 = new RadioButton();       
		
		
		//here i am assinging in particular div which id is "RadioDiv1" 
		
						Control myControl1 = FindControl("RadioDiv1");
						myControl1.Controls.Add(RadioButton1);
                        RadioButton1.Enabled = true;
                        RadioButton1.EnableViewState = true;
                        RadioButton1.AutoPostBack = false;
                        RadioButton1.ID = "RadioButton1";
                        myControl1.Controls.Add(new LiteralControl(""));                     
                        RadioButton1.CheckedChanged += new EventHandler(RadioButton1_CheckedChanged);
						
						
		//this is the checkedChanged event 				
		private void RadioButton1_CheckedChanged(object sender, EventArgs e)
        {
            if (!RadioButton1.Checked)
            {
                RadioButton1.Checked = true;

            }
            else 
            {
                RadioButton1.Checked = false;
            }
        }
		
		//But after clicking on the radiobutton1 the checked changed event is not fired, I am checking the value of Radiobutton1.checked == true 
		// even after select it gives me false .
		
				string user_ans = "";
                if (RadioButton1.Checked == true)
                {
                    user_ans += "A";
                }
