ASP MVC3 checkbox action without submit button - asp.net-mvc-3

Question

I am using ASP.net for a program with a number of check boxes and a submit button which initiates an action depending on the selected check boxes.
However, one of my check boxes should behave as this submit button, i.e, upon selecting/deselecting this check box, the same action as the button must be triggered. Can someone please help me in doing this (or perhaps direct me to a tutorial)
I have a controller class and model.
Thanks you
EDIT
The program look like:
#using(Html.BeginForm("controllername", FormMethod.Get)) {
#html.CheckBox("check1");
#HTMl.Checkbos("check2");
<input type="submit" value="Submit" />
}
Everything else is pretty much handled in the controller.

You can use javascript to listen to the check event of your check box and then invoke the form submit.
Assuming your markup of view is like this
<form id="yourFormId" action="user/post">
<input type="checkbox" class="optionChk" value="1" /> One
<input type="checkbox" class="optionChk" value="2" /> Two
<input type="checkbox" class="optionChk" value="3" /> Three
</form>
<script type="text/javascript">
$(function(){
$(".optionChk").click(function(){
var item=$(this);
if(item.val()=="2") //check your condition here
{
item.closest("form").submit();
}
});
});
</script>
EDIT : As per the question edit.
Change the CheckBox Helper method usage like the below to add a css class to the checkbox so that we can use that for the jQuery selection.
#Html.CheckBox("check1",new { #class="optionChk"})

imagining you have something like this:
#using(Html.BeginForm()) {
<label class="checkbox">
<input type="checkbox" name="chb_a" id="chb_a"> Option A
</label>
<label class="checkbox">
<input type="checkbox" name="chb_b" id="chb_b"> Option B
</label>
<label class="checkbox">
<input type="checkbox" name="chb_c" id="chb_c"> Option C
</label>
<label class="checkbox">
<input type="checkbox" name="chb_d" id="chb_d"> Option D
</label>
<button type="submit" class="btn">Submit</button>
}
you can write a simple jQuery to complement:
$(".submit").click(function() {
// find the <form> the element belongs and submit it
$(this).closest('form').submit();
});
and with this, all you need is to add a class named submit to any checkbox or more buttons if you want them to submit
for example:
<label class="checkbox">
<input type="checkbox" name="chb_e" id="chb_e" class="submit"> Option E
</label>

You can bind the click events on the checkboxes.
$( '.myCheckboxes' ).click(function () {
var clickedBox = $( this );
// now do something based on the clicked box...
});
If you need to know which checkboxes are checked, that's just another selector.
$( '.myCheckboxes:checked' ).each(function () {
// Now you have access to each checked box.
// Maybe you want to grab their values.
});
Just bind the checkbox to a click event. Assuming you have a way of uniquely identifying the checkbox that submits the form.
$( '#formSubmitCheckbox' ).click(function() {
$( '#myForm' ).submit();
});
