Init is executed when the component is compiled, so I wouldn't think you would be able to 'pass' a value into it in Init from outside the component. To set a variable within the init function you would just do that -- m.temp="Hello"
You would be able to pass values into compiled components by making the value global so the component can pull from the global namespace, or by setting up a field in the xml to transfer values in and out of the component.
<interface>
<field id="mydata" type="string" />
</interface>
