Start Timer from Javascript
===

The Timer is defined like this:  

    <asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="1000" Enabled="false" />

When calling `$find("<%= Timer1.ClientID %>")._startTimer();` I'm getting this error:  
> Microsoft JScript runtime error: Unable to get value of the property '_startTimer': object is null or undefined 

and when calling `$('#Timer1')._startTimer();` I'm getting this error:  
> Microsoft JScript runtime error: Object doesn't support property or method '_startTimer'

Any advice will be welcome.
