The solution is to add UseSubmitBehavior="False" So you end up with this for your button: 

 <asp:Button runat="server" Text="Send" OnClick="Button1_Click" UseSubmitBehavior="False" CssClass="btn btn-success btn-lg"></asp:Button>

The reason for this is that the default UseSubmitBehavor is set to True, which means that the Button control uses the client browser's submit mechanism. What you want however, is to use the asp postback mechanism (asp generates a block of scripts, part of it is the _doPostBack function:

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

Setting your UseSubmitBehavior="False" will trigger this function call and the postback to your server.
