Dynamic Button OnClick not firing

[=?Utf-8?B?Sm9obiBIYXJ0ZQ==?=]

Hi,

In the code behind of my ASP.net web page I have code written that is
dynamically creating a button. Here is a sample of how I define it.

//Define Variable
Button btnNext;

public void someMethod()
{
btnNext = new Button();
button += new EventHandler(this.btnNext_Click);
//then i add the control to the page, then call its click event
btnNext_Click();
}

When I clickthis button on the page, the page postsback and its onclick
event is never called (stepping through the code shows that it never gets
reached). If I click the button a second time, the method is called and it
works fine.

Im not sure if there is any more information I can give, and help would be
greatly appreciated
