Export camera animation from Maya


I am trying to animate my camera in Maya 2014 and export using OpenCollada.
My engine seems to read the camera position from the exported .dae if i ‘export the camera as lookat’.
However, i am not able to animate the camera using it as lookat.
This is the scene which gets generated for the camera:

<visual_scene id=“VisualSceneNode” name=“nissan_working”>
<node id=“camera1” name=“camera1” type=“NODE”>
<lookat>0 0 3.36702e-4 0 0 -4.999663 0 1 0 </lookat>
<instance_camera url="#cameraShape1"/>
<technique profile=“OpenCOLLADAMaya”>

How can i export my camera with all its animations?
