usercontrol 내 TextBox 텍스트 변경 이벤트

Question

usercontrol에서 txtPlanCode의 textchange 이벤트를 트리거하려고하지만 불행히도 내 textchange가 트리거되지 않습니다. 내 코드가 뭐가 잘못 됐어?

도와주세요 감사합니다 :) 사용자 컨트롤에

//CodeBehind of my page 
protected void ucPlan_OnTextChanged(object sender, EventArgs e) 
{ 
    TxtPlanDesc.Text = Session["PlanDesc"].ToString(); 
} 

//Client side (.aspx) 

<uc2:PlanID ID="ucPlanCode" runat="server" ucPlan_OnTextChanged="ucPlan_OnTextChanged" autopostback="true"/> 

//ucPlanID.ascx.cs 

protected void Page_Load(object sender, EventArgs e) 
{ 

} 

public string PlanID 
{ 
    get 
    { 
     return txtPlanCode.Text; 
    } 
    set 
    { 
     txtPlanCode.Text = value; 
    } 
} 

public bool AutoPostBack 
{ 
    get 
    { 
      return txtPlanCode.AutoPostBack; 
    } 
    set 
    { 
      txtPlanCode.AutoPostBack = value;

public event EventHandler TextChangeEvent; 

    protected void TextBox1_TextChanged(object sender, EventArgs e) 
    { 
     if (TextChangeEvent != null) 
      TextChangeEvent(this, e); 
    } 

<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>

<script runat="server"> 
protected void Some_TextChanged(object sender, EventArgs e) 
    { 
     // your code here
