button_Click event never hit - master-pages

Question

I have a web application utilizing master pages. For some reason, when I add a buttonclick event, the method is never hit. The page goes through the normal page_load events. How do I get my button click event to fire? Previously, This worked just fine, now this is happening in my whole application where the !page.IsPostBack always evaluates false from a button_Click
I have tried adding script Handlers and that doesnt seem to help
in the UI page:
<asp:Button ID="Button1" CssClass="btn btn-primary"
OnClick="putAccoutDetail" runat="server" Text="Save Changes" />
in the CodeBehind
protected void Page_Load(object sender, EventArgs e)
{
if (Session["Authenticated"] == null ||
Session["Authenticated"].ToString() != "true")
{
Response.Redirect("~/Login.aspx");
}
if (!Page.IsPostBack)
{
if (Session["UserID"] != null)
{
UserID = Convert.ToInt32(Session["UserID"]);
getUserData(UserID);
}
}
}
public void putAccoutDetail(object sender, EventArgs e)
{
string statusMsg = string.Empty;
var userInfo = db.UserMasts.FirstOrDefault(s => s.ID == UserID);
if (userInfo != null)
{
userInfo.UserName = txtUserName.Text;
userInfo.MilEmail = txtEmail.Text;
string base64 = Request.Form["imgCropped"];
if (base64.Length > 0)
{
byte[] bytes = Convert.FromBase64String(base64.Split(',')[1]);
String fileName = Guid.NewGuid().ToString() + ".png";
userInfo.PhotoPath = fileName;
ImagePhoto.ImageUrl = "/Images/Users/" + userInfo.PhotoPath;
using (FileStream stream = new FileStream(Server.MapPath("~/Images/Users/" + fileName), FileMode.Create))
{
stream.Write(bytes, 0, bytes.Length);
stream.Flush();
}
}
}
try
{
dHelper.LogAction("Update User Detail : " + userInfo.UserName);
db.SubmitChanges();
statusMsg = "Successfully Updated";
lblstatusMsg.Text = statusMsg;
lblstatusMsg.Visible = true;
}
catch(Exception ex)
{
statusMsg = "Update Failed";
lblstatusMsg.Text = statusMsg;
lblstatusMsg.Visible = true;
}
}

The issue was that the form had unhandled ASP validators on certain fields. I added a validation group to those and then handled them in the button_Click and all is working
