it should still fix some issue There is nothing in your code that checks the check state of the checkbox (on DOM ready), you are only attaching an event listener. If you want to trigger the event/handler you should either use change, triggerHandler or trigger method.
code :
//$(document).ready(function() {
    $('#agree_box').change(function() {
       $('#offer_fade').toggle(this.checked);
    }).change(); // execute the change handler(s) once on DOM ready
//});

I wish this helpful for you I got a logic. I can use events too when the particular check box clicked by Mouse or keyboard "Click" event, Actual code in the event is I can store some text (like "Mouse or Keyboard clicked") in Tag property of CheckBox. If the Tag property does not contain the above text or null mean, that CheckBox is not checked by Mouse or Keyboard.

This might help you Having trouble with checkboxes that are being pre-checked (when fetching record from mysql). So I am trying to create a way for users to edit a record in the database. One of the items on the form is a checkbox. I check to see if the record being edited has this feature, if it does I check the box. When I attempt to uncheck it, then use jquery/ajax to submit the form and update, it still sees the box as checked. Using firebug, I noticed that when I uncheck and check the box, it never removes the attribute checked='checked'. Any ideas?? , Use
code :
$('#account_ad_city').prop('checked'));

will help you You can use SparseBooleanArray for this
in your adapter, initialize and keep a sparse boolean array
code :
SparseBooleanArray mSelections = new SparseBooleanArray();
@Override
public View getGroupView(int groupPosition, boolean isExpanded, 
                                   View convertView, ViewGroup parent) {
    Group_Items gr = (Group_Items) getGroup(groupPosition);
    long group_id = getGroupId(groupPosition);

    if (convertView == null) {
        LayoutInflater inf = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inf.inflate(R.layout.expandable_group_items, null);
       // adding onClick listener on CheckBox for the very first time
       CheckBox chk=(CheckBox) convertView.findViewById(R.id.chk);
       chk.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                int position = (int) v.getTag();
                mSelections.put(position, !mSelections.get(position, false));
                ((CheckBox)v).setChecked(mSelections.get(position, false));
            }

       });
    }

    TextView title = (TextView) convertView.findViewById(R.id.title);
    title.setText(gr.getName());
    CheckBox chk=(CheckBox) convertView.findViewById(R.id.chk);
    chk.setTag(groupPosition);
    // reassigning checkbox to its ticked state
    chk.setChecked(mSelections.get(groupPosition, false));

    return convertView;
}

will be helpful for those in need You should call your method on ng-change of checkbox, to get correct changed value. Also add ng-model to get two way binding enable your checkbox value.
code :
<input ng-model="myCheckbox" type="checkbox" name="xxx" 
       ng-change='someFunction(myCheckbox)'">

wish of those help The checked() function echos by default. Use false in the last parameter to return the string instead of echo.
code :
$html .= '<input type="checkbox" name="CMBUserCheckbox" value="1" '.checked( $checkedByUser, 1, false).' />';
