How can I pass values from a controller to the view?

I am using sap.m and sap.ui.core.mvc with an XML view. In the view, I have a control like this:

<List

        id="list"

        items="{

          path: '/Posts',

          filters: [myFilter]

        }"

...

</List>

I have a controller for this view. How can I pass a value to myFilter above? In my controller, I have this in my onInit function:

this.myFilter = new sap.ui.model.odata.Filter("post_type", [{operator: "EQ", value1: "question"}]);

Thanks for your help!
