display data on selecting a checkbox

I have 3 checkboxes

<input type="checkbox" name ="chk[]" id="inlineCheckbox1" value="Permanent">Permanent
<input type="checkbox" name ="chk[]" id="inlineCheckbox2" value="Drive">Drive
<input type="checkbox" name ="chk[]" id="inlineCheckbox3" value="Contract"> Contract

and a div that contains 2 inputs

<div id="datetime"> 
    <input type='text' class="form-control" name="datee">
    <input type='text' class="form-control" name="timee" >
</div>

Checkbox Permanent and Contract can be selected normally, but i want that till the time Drive checkbox is not selected, the div should stay disabled, when the user selects Drive, he should be able to select values from div and if he again unchecks the Drive checkbox the div should get disabled again.

I tried to follow this code but it didnt seemed to work for me, can anyone please tell how it can be done
