You can call that function using Page.ClientScript method
something like:

asp.net Syntax (Toggle Plain Text) 
  1. Page.ClientScript.RegisterStartupScript(this.GetType(), "Test", "YourFunctionName();",true);

Or you can also attach a JavaScript event to a Server Control like:
asp.net Syntax (Toggle Plain Text) 
  1. Button1.Attributes.Add("onclick", "YourFunctionName();");

Or the other easy option would be
asp.net Syntax (Toggle Plain Text) 
  1. Response.write("<script>YourFunctionName(); <\script>")

Hi Sancti

Are you passing the parameter values to the function
As follows...
Response.write("<script>func('"+DropDownList1.SelectedIndex+"','"+ startDate+"','"+ endDate+"')</script>");
