In this example a handler has been added to a text field, which invokes the custom "search" function of the location picker field, 'LOCATION', whenever the value of the text field changes. The value of the text field is passed to the location picker's search.

function (helper, fieldName, value, valid, eventName) {
    if (eventName == 'CHANGE' && valid) {
        helper.invokeCustomFieldFn('LOCATION', 'search', value);
    }
}
