asp.net server tags not working inside an iteration

Question

my server tags are not being converted inside the for iteration. Have a look down bellow.

<% for (int i = 1; i < 30; i++)
{ %>
   <option value="<%=i%>">
   <asp:Literal runat="server" Text="<%=i%> <%$ Resources:Titles, dias%>"></asp:Literal></option>
<% } %>
<option selected="selected" value="30">
<asp:Literal runat="server" Text="30 <%$ Resources:Titles, dias%>"></asp:Literal></option>

above is my line of code, and its not working like it should because the result is down bellow:

<select id="ddlPeriodoCrescimento" style="color: black !important; height: 23px !important; margin:auto !important" onchange="loadCadastros()">    
    <option value="1">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="2">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="3">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="18">

    <option value="19">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="20">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="21">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="22">

    <option value="23">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="24">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="25">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="26">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="27">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="28">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option value="29">
        &lt;%=i%&gt; &lt;%$ Resources:Titles, dias%&gt;</option>

    <option selected="selected" value="30">
        30 Dias</option>
</select>

Why is not converting the servers tags <% %> inside the for iteration? any reason, am i forgetting something or is it a bug? if it is a bug any solution to work around it?
