javascript - DevExpress Button Click function does not work -

It should really be simple, but it does not work for me. I have this button: < Pre> & lt; Dx: ASPxButton ID = "BTN Start" Runat = "Server" text = "Start" Client InstanceName = "BTN Start" & gt; & Lt; Client Side Avent Clicks = "BTNstart_Link" / & gt; & Lt; / Dx: ASPxButton & gt;

and this JS:

  function BTN starttoset_link (S, E) {... logic ...}   
 But using firefox + firebug and setting a breakpoint in the function, I think that clicking on the button does not work. What am I doing wrong here?   
 
 
 The name of the javascript function (btnStartToetsing_Click) is different from the assignment  
  & Lt; Dx: ASPxButton id = "btnStart" runat = "server" text:  
  
 = "Start" Client InstanceName = "BTN Start" & gt; & Lt; Client Side Avent Clicks = "BTNstart_Link" / & gt; & Lt; / Dx: ASPxButton & gt; Function btnStart_Click (S, E) {warning (''); }
