Lock price in product detail

Hi Team, 

I'm trying to lock the price (readonly) with this code but seams to be not working.

			getCellControlsConfig: function(entitySchemaColumn) {
				var columnName = entitySchemaColumn.name;
				var enabled = (entitySchemaColumn.usageType !== Terrasoft.EntitySchemaColumnUsageType.None) &&
					!Ext.Array.contains(this.systemColumns, columnName);
				if (columnName == "Price") {
					var config = this.getDefaultCellControlsConfig(columnName, {
						enabled: false,
						caption: entitySchemaColumn.caption
					});
				} else {
					var config = this.getDefaultCellControlsConfig(columnName, {
						enabled: enabled,
						caption: entitySchemaColumn.caption
					});
				}
 
				if (entitySchemaColumn.dataValueType === Terrasoft.DataValueType.LOOKUP) {
					config.showValueAsLink = false;
				}
				if (entitySchemaColumn.dataValueType !== Terrasoft.DataValueType.DATE_TIME &&
					entitySchemaColumn.dataValueType !== Terrasoft.DataValueType.BOOLEAN) {
					config.focused = {"bindTo": "Is" + columnName + "Focused"};
				}
				return config;
			}
