You can fire the form submit event with jQuery using:
considering that your form has the id "HelpdeskView", please check in you generated html if the form has this id
$("#HelpdeskView").submit()
probably you'll have to write your form that way
@using(Html.BeginForm("HelpdeskView", "Helpdesk", FormMethod.Post, new{id="HelpdeskView"}))
or you could do the this way
@using (Html.BeginForm("HelpdeskView", "Helpdesk", @Model))
{
<input type="submit" value="Save & Return to Menu" name="SaveAndReturn" id="SaveAndReturn" />
}
then in your click method you just change the value of the $("#ReturnToList")
the click event will be called first so the form will be submited
hope it helps and sorry, my english is bad
