How would you bind a dynamic value to a dynamic component in Handlebars/EmberJS

I'm creating a dynamic table component (one row per model), that will include components dynamically (one column for each object in config, each object relates to a key in a model).

I'm trying to bind the model key to the dynamic model.

Any ideas on how to do that given the following?

Config object:

EDConfig: {
    controller: this, 
    modelType: 'EscalationDetailModelGroup',
    table: {
        cols: [{
            header: 'Escalation Time',
            cname: 'form-input-text',
            content: {
               value: model.escalationTime //obviously this wont work
            }
        },{
            header: 'Most Complex Alarm Level',
            field: 'mostComplexAlarmLevelDispatched',
            cname: 'form-input-text',
            content: {
               value: model.escalationTime //obviously this wont work
            }
        }]
    }
};

Model array:

modelRange: [{
    id: 1,
    escalationTime: '3 hours',
    mostComplexAlarmLevelDispatched: 'N/A'
}, {
    id: 2,
    escalationTime: '45 minutes',
    mostComplexAlarmLevelDispatched: 'Level 3'
}]

Template:

<table>
    <thead>
        <tr>
            {{#each col in config.table.cols}}
                <th>{{col.header}}</th>
            {{/each}}
        </tr>
    </thead>
    <tbody>
        {{#each record in modelRange}}
        <tr>
            {{#each col in config.table.cols}}
            <td>
                {{component col.cname content=col.content}}
            </td>
            {{/each}}
        </tr>
        {{/each}}
    </tbody>
</table>
