Convert ASP.Net Button to HTML Button with events

I have the below line of asp code:

<asp:Button ID="btnLogin" CssClass="btn btn-success" Text="Login" OnClientClick="return FunForLoginValidation()" runat="server" OnClick="btnLogin_Click"/> 

i wanted to write the same by using <input type>

i tried the following:

<input class="grey-button" type="submit" name="commit" value="Sign In" OnClientClick="return FunForLoginValidation()" runat="server" onserverclick="btnLogin_Click">

Is it a correct way to write this?
